A selective college would like to have an entering class of 1200 students. Because not all students who are offered admission accept, the college admits more than 1200 students. Past experience shows that about 70% of the students will accept. The college decides to admit 1500 students. Assuming that students make their decisions independently, the number who accept has the B(1500, 0.7) distribution. If this number is less than 1200, the college will admit students from its waiting list. Use 4 decimal places in answering each of the following questions. (a) What are the mean and standard deviation of the number X of students who accept? mean: standard deviation: (b) Use the normal approximation to find the probability that at least 1000 students accept. answer (with continuity correction): (c) If the college decides to increase the number of admission offers to 1700, what is the probability that more than 1200 will accept?
