6) Suppose 78% of students say they are satisfied with their college experience. Assuming a binomial situation, round all answer to the nearest ten thousandth or 100™ percent [.1234 = 12.34%]. Show what you put into your calculator. a) If 12 students are randomly selected, find the probability that exactly 6 say they are satisfied. b) If 12 students are randomly selected, find the probability that less than half are satisfied. c) If 12 students are randomly selected, find the probability that more than 9 are satisfied. d) If 300 students randomly selected, find the probability that at least 225 are satisfied. e) When 300 students are randomly selected, find the mean and standard deviation for the number who are satisfied.
