A college has a limited enrollment summer course that only accepts 50 students, selected at random from the more than 2000 qualified students who apply each year. Of these applicants, 22% have completed 2 or fewer years of college. Suppose the registrar calculates the annual proportion p, with, hat, on top of students accepted into the course who have completed 2 or fewer years of college. Which of the following distributions is the best approximation of the sampling distribution of
p, with, hat, on top?

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
