The document discusses a dataset on rocket fuel conversion rates for a control and treated group throughout the day. A chart shows conversion rates are highest around 4pm. One colleague suggests exposing ads at 4pm daily since conversion rates seem highest then. However, the document asks if you agree and to explain, as well as how to modify the experiment design to draw more accurate conclusions and what the potential costs might be.

Education

(The Rocket Fuel Case) Based on the dataset rocket_fuel.csv in our Assignment 3, we can create
a chart with conversion rates for the control and treated group
as a function of hours within a day (excluding the period between midnight and 8am). The chart
looks as follows:
Suppose your team is in charge of the advertising timing decisions.
(1) One of your colleagues suggested that we should expose our ads to customers around 4pm
every day as the average conversion rate at that time seems the highest.
According to the chart, do you agree or disagree? Explain your argument.
(2) To better serve your teams purpose, how would you modify the current experimental design to
draw more accurate conclusions? What might be the potential cost of that
modification?

The rate of photosynthesis, as indicated by oxygen production, in plant cells was measured as the light intensity was increased in four experiments. All other factors except for temperature and carbon dioxide where kept constant. The results of the four experiments are shown in the following graph. Which of the following best explains why photosynthesis did not appear to be occurring in Experiment 4. Select one: A. The light intensity was too low to enable the light-dependent reactions of photosynthesis to proceed, and so no oxygen was produced. B. The enzymes associated with photosynthesis were denatured, stopping the process from occurring. C. The carbon dioxide concentration was too low to allow photosynthesis to occur. D. The rate of photosynthesis was so low, that all the oxygen produced was used up by cellular respiration in the plant..

The protocol will use the following building blocks. The Inner Product Prediction Challenge for RSA. Recall that the RSA based cryptographic constructions involve a composite integer NN where N=pq for large primes p,qN. Additionally, a public exponent e is chosen along with N, whereas the secret exponent d satisfies de =1mod(p1)(q1) and is known by only one of the two players. Recall that de=1mod(p1)(q1) ensures xed=xmodN, whereas given (N,e), recovering d is as hard as factoring N. In the protocol below we will write (N,e,d)RSA.Gen() to indicate that (N,e,d) are generated as above. Finally, recall that the RSA assumption assumes that when (N,e,d)RSA .Gen () and xZN is drawn, one cannot output x if given (N,e,y) where y=xe (of course if one is given (N,e,d,y) then one can simply compute x=yd ). In homework 6 1, problem 3 we saw the following "inner product prediction" version of the RSA game: given (N,e,y,r) where (N,e,d)RSA. Gen(),xZN,y=xe and r{0,1}n where n=log(N), output x,r. We showed that any adversary who can win the inner product prediction game for RSA with probability 1/2+ for non-negligible >0 can be used to build (via the techniques of Goldreich-Levin) another adversary who can break the RSA assumption with non-negligible probability. Blum's Commitment Scheme. The protocol below will use Blum's non-interactive commitment scheme as a building block. While Blum's scheme allows Alice to commit to a single bit, Alice can commit to an n-bit string by committing independently to each bit. For an n-bit string u{0,1}n, we write (z,k)Com(u) to indicate that z and k are respectively the collections of commitment and decommitment strings when Blum's scheme is used to commit to each bit of x. Recall binding says that for any z, there is at most one k such that the decommitment procedure succeeds when run with input (z,k). Recall the hiding game for this commitment scheme is played between a challenger C and adversary A as follows. - A sends (u0, u1) to C where u0,u1{0,1}n; - C draws b{0,1} and (z,k)Com(ub) and sends z to A; - A sends b{0,1} to C signaling the end of the game; A wins if b=b. Hiding security demands that no efficient adversary can win this hiding game except with probability 1/2+ for negligible >0.Zero-Knowledge Proofs. Our OT protocol will use a ZK proof system as a key building block for one of the parties to prove to the other that a particular quantity in the protocol has been computed correctly. As a simple example to help understand the role that the ZK proof plays, imagine that early on in the protocol, A sends z to B where (z,k)Com(0). Then while z is supposed to be a commitment to 0 , hiding says that B cannot actually tell what value is hidden inside, so it is possible that an adversarial A might have actually drawn (z,k)Com(1). In this case, it might be useful to have A prove to B using a ZK proof that in fact z is a commitment to 0 . For this to work, the statement is " zL " where membership in L holds whenever ther.

The purpose of this project is to develop a code which will conpare a pair of text filen containing English sentences from a vocabulary standpoint. Fefer to the text. content as "text01" and "text02". The folloving interaction with the uaer takes place: Enter the filename of text1: filenamel.txt Enter the filename of text2: filename2. txt Select a menu option: Enter 1 for total character count both files (1etcers only) Enter 2 for total word count both files (no punctuation) Enter 3 for unique word count both files Enter 4 for unique word count only in textl and only in textz Enter 5 for unique words eount in both files Enter 6 to quit Each of the first five options should be handled by one function that you write. For example, with option 1, this call would be made: ch1, ch2 = charcount (text1, text 2) t handle option 1 where text1 and text2 are strings of text read from the selected files and ohl and ch2 are the total number of characters in each file. In a similar manner the other functions would be: wordi, word2 = wordsopt2 (text1, text2) i handle option 2 etc for the other options - use good naming conventions. You will also need a menu function which presents the menu and a while loop in main which continues to present the menu until option- 7 is entered. You will use the set function and operations for [options 3, 4, and 5. The first pair of files will be: Viait to Water Park Grade 1 . txt Blocking Beethoven Grade 5.txt The first file is for elementary school readera in grade 1 and the recond is for grade 5. Using your program output metrics can you draw any conclusions based on number of unique words? E.g. Can you conclude that the grade 6 text is verbally more advanced?

THE PROBLEMATIC WHISTLEBLOWER Paul O'Doherty is the ethics officer for a medium-sized petroleum company. The company has a comprehensive ethics program that is his responsibility. The program includes a code of business conduct that outlines the values that guide behaviour, identifies conflicts of interest, specifies appropriate and inappropriate practices, and provides an approach to reporting violations or suspected wrongdoing. One aspect of the reporting system is an employee Hotline; employees can contribute in written form, such as by email, or orally, by telephone or in person. Participants must identify themselves and all communications go directly to Paul. He reports directly to the corporate secretary and legal counsel; the identity of the employee is not disclosed and confidentiality is maintained except in rare cases where there is legal action. Paul is a member of the Ethics Practitioners' Association of Canada (EPAC). According to EPAC, the skills of an ethics officer include "facilitating constructive dialogue on ethics-related issues, analyzing ethics issues and problems, and providing coherent, realistic solutions to ethical issues." 31 His job has been rewarding and he has enabled the company to keep abreast of developments in the ethics area. The company has received awards for its ethics program and is recognized as a leader in corporate ethics. Recently, Paul has been experiencing a problem with the Hotline component of the ethics program. An employee is making numerous complaints to the Hotline, almost weekly. The complaints cover many aspects of the employee's department: unfair treatment by a supervisor, stealing of office supplies by coworkers, management favouritism in assigning holidays, reporting an employee who is moonlighting. and quality of service given to customers. All of the complaints have been investigated according to the procedures outlined in the corporation's reporting guidelines. The investigations have been costly, in terms of both money and time. None of the complaints has been determined to be justified and many lack credibility. Paul has reluctantly concluded that the employee is a whiner or troublemaker, but he cannot state this to others. It appears that the employee's reporting practices have been damaging to department morale. The challenge now is to decide whether something should be done about the situation. Questions What stakeholders are involved in this situation? What actions should be taken to address this situation? What are the ethical implications of each action? What ethical principle or principles should be followed in resolving this situation?.

The process for converting present values into future values is called compounding or discounting. This process requires knowledge of the values of three of four time-value-of-money variables. Which of the following is not one of these variables? Line A: 0%, 21%, 11% Line B: 0%, 21%, 11% Line C: 0%, 21%, 11% Investments and loans base their interest calculations on one of two possible methods: the simple or complex interest and the compound or uncomplicated interest methods. The principal of the time value of money is probably the single most important concept in financial management. One of the most frequently encountered applications involves the calculation of a future value. The process for converting present values into future values is called . This process requires knowledge of the values of three of four time-value-of-money variables. Which of the following is not one of these variables? The duration of the investment (N) The inflation rate indicating the change in average prices The interest rate (I) that could be earned by invested funds The present value (PV) of the amount invested All other things being equal, the numerical difference between a present and a future value corresponds to the amount of interest earned during the deposit or investment period. Each line on the following graph corresponds to an interest rate: 0%,11%, or 21%. Identify the interest rate that corresponds with each line. Line A: Line B: Line C:Investments and loans base their interest calculations on one of two possible methods: the interest and the interest methods. Both methods apply three variables-the amount of principal, the interest rate, and the investment or deposit period-to the amount deposited or invested in order to compute the amount of interest. However, the two methods differ in their relationship between the variables. Assume that the variables I, N, and PV represent the interest rate, investment or deposit period, and present value of the amount deposited or invested, respectively. Which equation best represents the calculation of a future value (FV) using: Compound interest? FV=(1+I)N/PVFV=PV+(PVIN)FV=PV(1+I)N Simple interest? FV=PVINFV=PV +(PVIN)FV=PV(PVIN)Identify whether the following statements about the simple and compound interest methods are true or false. Nicholai is willing to invest $35,000 for six years, and is an economically rational investor. He has identified three investment alternatives (A, B, and C) that vary in their method of calculating interest and in the annual interest rate offered. Since he can only make one investment during the six-year investment period, complete the following table and indicate whether Nicholai should invest in each of the investments. Note: When calculating each investment's future value, assume that all interest is earned annually. The final value should be rounded to the nearest whole dollar..

The problems associated with the nomenclature include: a) Scientific name not italicised b) Scientific name not underlined c) Incorrect capitalisation d) Unnecessary restatement of genus e) No problem The Linnaean system of nomenclature is widely used, but often incorrectly applied. Identify the problems associated with the nomenclature in each of the following sentences. See The nature of data lesson. "The most common species recorded on our transects was Eucalyptus Racemosa ssp. Rossii (58%). The remaining 42% comprised four species that are locally common- E. Mannifera, E. Macrorhyncha and E. Polyanthemos." "Many Australian tree species are widely grown in California, especially those in the genus Eucalyptus. There are over two hundred species of Eucalyptus currently being grown in California, several of which have naturalized. Dr. Matt Ritter will discuss the implications of naturalized eucalypts in California, the controversy associates with their propagation and removal, and the widespread myth of their allelopathy." We examined climate sensitivity in Podocarpus lawrencei-Australia's only alpine conifer. Most of the Australian macropods have suffered significant declines in numbers and/or distribution since European settlement, some to extinction. There has been little adverse effect on the larger kangaroos (red kangaroo (Macropus rufus), western grey kangaroo ( M. fuliginosus), eastern grey kangaroo (Macropus giganteus).A composite linkage map was constructed from four individual maps for the conifer Picea glauca. Comparisons with two other composite linkage maps developed for the species complex P. mariana, P. rubens, and for P. abies revealed remarkable conservation of the gene content. The combined information from these three Picea species validated and improved large-scale comparisons between genera in the family Pinaceae by allowing identification of linkage groups between Picea and Pinus, and between Picea and Pseudotsuga menziesii. Evidence indicated instability in part of the P. menziesii genome. Overall, the macrostructure of the Pinaceae genome was well conserved, which is notable given the Cretaceous origin of its main lineages..

The patient is a male, age 17 from Bethlehem, Pennsylvania. He was admitted to the clinic with a deep, red, swollen abscess on the back-right shoulder. The patient is a student at a local high school where he wrestles for the varsity team. The patients dad is a high school teacher and wrestling coach and his mother is a human resources manager. The family has a history of high blood pressure (paternal) and breast cancer (maternal). The teenager enjoys hanging out with his friends and playing video games. Nine days ago after a match against a rival team, he noticed a red lump on his shoulder. Four of his teammates had similar sores on their arms, chest, and face. The young mans father applied a topical antibiotic ointment to the area and covered it with an adhesive bandage. A few days later, the young mans parents noticed that the bump appeared red and somewhat swollen. Concerned, the boys father again applied antibiotic ointment, applied an adhesive bandage, and held the son out of practice. The next day, the sore still appeared raised and inflamed. After a few days, it began to feel hard and hot to the touch, and the patient often complained of tiredness and headaches. He was febrile upon admission to the clinic. The abscess on his shoulder is roughly 1.5 inches in diameter, with a yellowish center and weeping, crusted tips. Let's learn a little bit more about the skin. Complete the blanks: (1),(2) Skin consists of two principal parts, the epidermis, and the ___________(2) ________________. The ___________(1) ________________ is the thin outer portion, composed of several layers of epithelial cells. The outermost layer of the epidermis, the stratum corneum, consists of many rows of dead cells that contain a waterproofing protein called keratin. The ___________(1) ________________, when unbroken, is an effective physical barrier against microorganisms composed mainly of connective tissue. The ___________(2) ________________ is the inner, relatively thick portion of skin, composed mainly of connective tissue. The hair follicles, sweat gland ducts, and oil gland ducts in the dermis provide passageways through which microorganisms can enter the skin and penetrate deeper tissues. Perspiration provides moisture and some nutrients for microbial growth. However, it contains salt, which inhibits many microorganisms; the enzyme lysozyme, which is capable of breaking down the cell walls of certain bacteria; and antimicrobial peptides. Sebum, secreted by oil glands, is a mixture of lipids (unsaturated fatty acids), proteins, and salts that prevents skin and hair from drying out. Although the fatty acids inhibit the growth of certain pathogens, sebum, like perspiration, is also nutritive for many microorganisms..
