Can someone help me with this probability and statistics question?
A selective college would like to have an incoming class of 1200 students. Since not all admitted students accept, the college admits more than 1200. Past years have shown that 70% of those admitted will accept. The college admits 1500 students. Assuming the students make their decisions independently, the # who accept has the B(1500, .7) distribution. If this # is less than 1200, the college will admit wait list students.
a)what are the mean and standard deviation of the number X of students who accept?
b)use the normal approximation to find the probability that at least 1000 students accept?
c)the college does not want more than 1200 students. what is the probability that more than 1200 accept?
d)if the college decides to increase the # of admission offers to 1700, what is the probability that more than 1200 will accept?
