5. The American Red Cross says that about 11% of the US population has type B blood. In a local blood drive, if the blood types of donors are independent, what is the probability that at least two of the next 10 donors have type B blood? Round your answer to three decimal places if necessary.

6. There are 6 red, 5 white, and 9 blue marbles in a small sack. If three marbles are selected at random without replacement, what is the probability exactly one is white? Round your answer to three decimal digits if necessary.

In a certain population the frequencies of alleles determining the ABO blood groups were estimated as 0.5 for IO , 0.3 for IA and 0.2 for IB. Assuming random mating, what is the expected frequency of blood type A individuals?

10. A psychologist suspects that poll results on sensitive issues are being affected by the gender of the pollster. The table below summarizes the results of whether male respondents agreed with the pollster, based on the pollster’s gender. Perform a hypothesis test to evaluate the claim that agreement is dependent on the pollster’s gender, then interpret your results. Your answer should include a test statistic, p-value, and conclusion about dependence. Use​​Gender ofPollster​​​MaleFemale​​Men who agree560​308​​Men who disagree240​92​

15. The 95% confidence interval for the mean length of frog jumps is (12.64, 14.44) cm. What does it mean that we have 95% confidence that the population mean is covered by the interval from 12.64 cm to 14.44 cm?

2. A given company has 1200 employees. Of these employees, 800 have a computer science degree and 600 have a mathematics degree. If 1000 employees have either a computer science degree or a mathematics degree, what is the probability a randomly selected employee has both a computer science degree and a mathematics degree? Round your answer to three decimal digits if necessary.
