Suppose 15 students full-time collegestudents are randomly selected and asked whether they are working.(a) (3 points) Explain (as best as you can) why this is a binomialexperiment.
(b) (1 points) Find and interpret the probability that exactly10 students say they work. (c) (1 points) Find and interpret theprobability that at least 10 students say they work. (d) (2 points)Find the expected value and the standard deviation of this binomialrandom variable. (e) (2 points) Which event is more likely, A) atmost 11 students work or B) 14 or more students work ? How do youknow?
