Students who perform well on a midterm exam in a statistics class will typically, but not always, also do well on the final exam. Based on exam scores from 353 students over 10 years, a least-squares line found a student's final exam score can be predicted to be 0.45 times their score above the midterm exam average. Therefore, a student who scored 19 points above the midterm average can be expected to score around 8.55 points above the final exam average.

This is another example of regression to the mean: students who do well on the midterm will on
average do less well, but still above average, on the final. We expect that students who do well
on the midterm exam in a course will usually also do well on the final exam. An instructor
looked at the exam scores of all 353 students who took her statistics class over a 10-year period.
The least-squares line for predicting final exam score from midterm-exam score was . (Both
exams have a 100-point scale) Octavio scores 19 points above the class mean on the midterm.
How many points above the class mean do you predict that he will score on the final? Score:
This is another example of regression to the mean: students who do well on the midterm will on
average do less well, but still above average, on the final.
Solution
so he would be 0.45*19 above the average = 8.55 above average on final

This starts off with five points equally spaced along the x-axis. Thus they initially lie on a line with intercept zero and slope zero. Then each point is nudged randomly, as if they were moving under Brownian motion (like pollen grains in water seen under a microscope). Run the file to see the five points as they slowly drift about randomly But there is a problem! The animation is supposed to update the best-fit line but it just stays motionless along the x-axis. Study the code to see how it works. Then add one or two lines at the indicated spot, so the best-fit line updates every time the points drift.

The Thiessen polygons method is a common method used to interpolate precipitation data over time. Two common methods to develop a unit hydrograph for ungagged basins are the Snyder and the SCS. The temperature is the only environmental factor affecting potential evapotranspiration. Both the phi Index and the Green-Ampt are common methods in engineering to estimate water infiltration. Early this week the Mason Campus was closed due the effects of Winter Storm Titan. This storm is a clear example of a convective precipitation event. The Time of rise (Tr) as defined when using the unit hydrograph method represents the total duration of the runoff. Base flow in a stream results from flows from the groundwater into the stream. Hydraulics is the field that studies the occurrence, distribution, movement and properties of water on earth. Rain gages are instruments used to measure precipitation at a point scale. On the other hand radars such as the NEXRAD can be used to measure precipitation over a larger spatial scale. Important parameters for design storms are volume, duration, frequency and intensity The rational method is designed to calculate runoff for very large watersheds (e.g.: Mississippi river watershed) given the runoff coefficient, rainfall intensity and watershed areas. River flow is usually determined by measuring water levels and applying a rating curse to convert water levels to discharge. Solution 1. True - theissen polygon method is the most common method used to calculate precipitation data over time and when there is more than one measurement.in this the area is divided into no.of polygons eachone around a measurement point,and then take a weighted avg of polygon based on size of each polygon. 2. True - these both snyder and SCS are the two methods along with commons dimensionless method.in these three methods snyder is the mostly used method to develop unit hydrograph for ungagged basins. 3. False - the evapotransparation process is not only effected by temperature but also due to soil characteristics,physical attributes of vegitation,water availaability etc. 4. False - green and ampt method is used to estimate water infiltration along with some other methods like richards equation,hoston equation,darchys law etc.and phi-index method is used to compute excess rainfall hetrograph using total rainfall hetrograph using constant phi. 5.True - this strom is a convective precipitation as these type of rainfall mostly occurs in the form of snow or freezing liquids 6. False - the time of rise is defined as the time passt a specified point in rising limb. 7. True - the portion of stream flow that is not runoff and results from seepage of water from the ground into a channel slowly over time. 8. False - hydraulics is a science and technology concerned with the conveyance of liquids through pipes and channels, especially as a source of mechanical force. 9. True - NEXRAD is a network of 160 high-resolution S-band Doppler weather radars opera.

There are twelve astrological signs: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. For example, your sign is Pisces if your birthday falls between February 19th and March 20th. Assuming all the astrological signs are equally likely for birthdays, find the probability that among a set of n people, at least two have the same astrological sign. Hint: remember the pigeonhole principle. Find the minimum number of people needed to guarantee a greater than 50% chance that two of them share the same astrological sign. Solution a) total no of events(sample space) = 12^n Atleast two having same sign = total - no one having same sign =(12^n) - (12*11*10*...*(13-n)) if n<=12 = 0 if n>12 by pegion hole principle P(E) = 1 - ( ( 12*11*10*....*(13-n) ) / 12^n ) ----if n<=12 = 0 ------------------------------- ------if n>12 b)P(E) > 1/2 So 12*11*10...*13-n / 12^n < 1/2 Solving we get n = 5.

There are several documentaries about the engineering disasters associated with Hurricane Katrina There are equally as many publications on the topic. Review at least three publications (not blogs or media reports or public opinion-based sources) to address the following questions What failed Why it failed Possible corrective actions Who was at fault and why Write a 3-5 page review addressing the afore-mentioned topics and include the following as well Describe in detail what ethical issues may have been partly/wholly responsible for the failure Be sure to address lack of professionalism or conscientiousness that may have helped lead to this failure You must cite references appropriately and there must be at least three credible references. Solution Engineering Review of the Disaster caused by Hurricane Katrina Even though 5 engineering review bodies operated separately, all of them reacted to IPET’s work, the main and finest funded of the study groups. Volumes 2 through 7 of the IPET “draft final” report divide the results into six broad sections: 1. Geodetic Vertical and Water Level Datums 2. Hurricane Protection System 3. The Storm 4. The Performance of the Levees and Floodwalls 5. Performance of Interior Drainage and Pumping 6. The Consequences; and Engineering and Operational Risk and Reliability Analyses The report is more than 6,000 pages extensive so far, and the last section on risk and reliability has not yet appeared. The NAE/NRC team and the ASCE team both prepared their commentary to conform to the IPET pattern. In reviewing a study of this kind, it is significant to keep in mind that critiques may address the quality of the design and construction for facilities in place at the time of the hurricane or the adequacy of the post-hurricane investigations described in the report. For example, one might find that the wind and water levels used for the design calculations were not adequate but that the hind-casting calculations of the hurricane’s effects described in the report are excellent. The NAE/NRC team and the ASCE team had similar reactions, with some minor differences of detail. The detailed study of the geodetic levels revealed considerable room for confusion and error. Two different benchmark levels were used in creating the levee system. In some cases, the water levels were expressed against one benchmark and the height of the levees against another. Furthermore, there seemed to be no consistent effort to monitor subsidence of the levee system or its components. The focus was on building the levees to the “authorized” elevations without considering whether the corresponding water elevations were measured from the same base or whether subsequent settlement and subsidence might make the authorized levels irrelevant. Ethical Issues: All of the review teams found that the hurricane protection system was a system in name only. Planning and system-wide design were confused by political and short-term economic considerations over.

There are many famous (more properly, infamous) examples of catastrophic failures of major engineering structures and systems. Use the Internet to look up each of the following and briefly describe whether the failure involved brittle or ductile failure initially (as a cause) and brittle or ductile failure overall (macroscopically). Tacoma (WA) Narrows Bridge, known as Galloping Gertie Minnesota I-35W Bridge Space Shuttle Challenger Space Shuttle Columbia RMS Titanic Aloha Airlines Flight 243 Solution a. Tacoma bridge failure is considered a ductile failure, because the collapse due to the wind vibrations lasted for long time so that no human casualities were made. Only one dog was the casuality. 2. The failure of I-35 bridge in Minnesota was a brittle failure because it occured suddenly and caused enormous catastrophic consequences. c. Space shuttle Challenger disaster occured due to the occurence of the brittle failure cracks in O-rings which allowed the fuel leakage and thereby the explosion. No one in the shuttle surviced, therefore it is a brittle failure. O-rings are ductile in nature but, at low temperature they become brittle, so such failures come in category of ductile-to-brittle transition failures. d. Space Shuttle Columbia failure occured due to the damage to the thermal shielding tiles from impact with a piece of foam, which fell from the insulation of an external tank during the take off. Failure occured while returning to the earth, while its speed was very very high, and wing experienced a high temperature of 1540 degree celsius. Damage to the thermal shield panel was tested to be a brittle failure, and therefore it also comes in category of brittle failure. e. RMS titanic was floating at very cold temperature and when near freezing temperature was met, tests showed that steel became extremely brittle. It was also a ductile-to-brittle transition failure. Overall ship sunk in 2 hours and about 15 minutes, so overall it could be considered a ductile failure, but no help was available in that time. f. It was a gatigue failure, which progressed in 19 years, but the end failure was brittle, therefore a brittle failure. Overall (maroscopically) failure was a ductile failure, since it happened due to the corrosion and fatigue of 19 years..

The waiting time Y until delivery of a new component for an industrial operation is uniformly distributed over the interval from 1 to 5 days. The cost of this delay is given by U = 2Y2 + 3. Use the method of transformations to derive the density function of U. I have found that the distribution function of Y is P(Y <= y) = (y-1)/5. Why is this? Solution You know F_Y(y) because Y is uniformly distributed. F_Y(y)= integral_1^y 1/4 dx= (y-1)/4 when y in [1,5] = 0 when y<1 = 1 when y>5 1/4 because the length of the interval [1,5] is 4. the density function is f_y(y)=1/4 when y in [1,5]..
