A sporting goods manufacturer was asked to sponsor a local boy in two fishing tournaments. They claim the probatility that he will win the first toumament is 0.7 . If he wins the first toumament, they estimate the probabality that he will also win the second is 0.6 . They guess that it he loses the first tournament, the probablity that he will win the second is 0.5 . Complete parts a through e below. a) According to their estimates, are the two toumaments independent? Explain your answer. A. No; no events are independent. B. Yes, al events are independent. C. Yes; the cutcome of the first tournament has no impact on the second tournament. D. No; the outcome of the frst toumament determines the probability of winning the second toumament. b) What's the peobabilty that he loses both tournaments? (Type an integer or a decimal. Do not round.) c) Whars the probeblity that he wins both tournaments? (Type an integer or a decimal. Do not round.) d) Let random variable X be the number of tournaments he wins. Find the probability model for X . e) What are the expected value and sandard deviation of X? The expected value of X is (Type an integer or a decimal. Do not round.) The standard deviation of X is (Round to three decimal places as needed.).

A species of bent grass has a gene that controls whether it is tolerant of (or susceptible to) copper poisoning The more copper that is present in soil, the greater the survival and reproductive advantage tolerant plants have over susceptible plants, When copper levels are particularly high, susceptible plants die as seedlings before reaching reproductive maturity. In contrast, where soil- copper levels are normal, susceptible plants grow and reproduce much better than copper- tolerant plants. Bent-grass reproduction does not rely on animals, as its pollen and seeds are both carried by wind. The tolerant phenotype is inherited in a completely dominant fashion over the susceptible phenotype. In an abandoned copper-mine sile, a sample of 100 mature bent-grass individuals was taken to a genetics lab, and the genotypes for copper tolerance were identified: 55 homozygous tolerant and 45 heterozygous. Is there evidence for evolution of the copper- tolerance gene in this population of bent grass at the abandoned mine site? If so, what might be causing the evolution? Is there evidence for more than one evolutionary mechanism acting?.

A small open economy produces two goods: machines ( M ) and food ( F ) under CRS. Production of machines requires labour ( L m ) and capital ( K ) , while the production of food requires labour ( L f ) and land ( T ) . All other standard assumptions of the Specific Factors Model are satisfied. (a) Analyse graphically what happens to employment and output in both sectors when the land area in the production of food increases. How will that affect the rewards to all factors of production? (b) Suppose the world price of machines increases. Analyse graphically what happens to employment and output in both sectors and how will that affect the tewards to all factors of production..

A small medical clinic needs a relational database for its medical practice. As a first step, the clinic has asked youtto develop a data model for the database with the following business rules and requirements: a. Although a patient can make many appointments and a doctor can have many appointments, each appointment is made with only one doctor and one patient at a time. b. An appointment yields a visit with the doctor. c. After each patient visit, an invoice is generated. d. A patient may pay the invoice in one or more payments; each payment is associated with one invoice. First, identify necessary entities, relevant attributes of the entities, and relationships between entities. Then put these together to create an ER diagram. Besides the primary key columns, and foreign key columns (as needed), please be sure that the following attributes are also included in appropriate entities in your ER diagram: Names of doctors and patients along with their phone numbers; appointment date and time; visit date and visit time; date and amount of invoice; date and amount of payment received; and any other necessary attributes. - Include a text box in the diagram in which you should write your full name. - Make sure that all of the attributes in each entity are visible. - Save the completed diagram on your computer (from the menu, select File > Save Model As...) and name the file as your last name. Upload the your-last- name mwb file to Canvas..

A small college has 500 male and 600 female undergraduates. A simple random sample of 50 of the male undergraduates is selected and, separately, a simple random sample of 60 of the female undergraduates is selected. The two samples are combined to give an overall sample of 110 students. The overall sample is a simple random sample. a stratifi ed random sample. a multistage sample. all of the above..

A scientist wants to examine living cells lining the respiratory tract to determine how the cells use tiny hairs to move dirt and mucus away from the lungs. Which of the following instruments would be best, and why? a transmission electron microscope, because it has high resolution a scanning electron microscope, because it can be used to observe whole cells without slicing them a light microscope, because it allows observations of whole, live cells a scanning electron microscope, because it can reveal structures on cell surfaces.

A researcher was interested in how different groups perceive psychologists. She asked college students, psychologists, lawyers, and people in the general public how important they thought psychologists were to the current United States society (1 = Not important), 10 = Very important). Use a simple ANOVA to test for differences among the groups and run a Tukey to compare each group. College Students Psychologists Lawyers General Public 4 6 5 4 3 7 6 4 5 5 7 5 3 7 8 5 5 6 4 3 Test selected: Ho: Ha: DF: Critical Value: T-Statistic: Decision: Compare Factors Group Group Sig EMBED Equation.3 Decision Describe Findings College General Psychologists Lawyers Students Public 4 6 5 4 3 7 6 4 5 5 7 5 3 7 8 5 5 6 4 3 .

A researcher wants to know if excessive social media use causes academic problems. She surveys 1000 high school students and asks them how many hours per day, on average, they use various social media applications. She then matches this information to their high school GPA. She finds a negative correlation with high social media use associated with lower GPAs. Is this a good or bad design for making a causal conclusion, i.e., the conclusion that independent variable causes the dependent variable?.
