About 68% of all U.S. public high school graduates in 2011went on to attend college that fall. At Heavenly High, therewere 270 graduates and 210 of them went on to attendcollege in the fall (78% of them).Use the normal approximation to the binomial distributionto estimate the probability of randomly selecting 270 highschool graduates with 210 or more of them attendingcollege.(a) Find the mean.(b) Find the standard deviation.(c) Find the z-score.(d) Find the probability.

Business weekly conducted a survey of graduates for 30 top MBA programs. On the basis of the survey assume the means annual salary 10 years after graduation is $162,000. Assume the standard deviation is $40,000. Suppose you take a simply random sample of 39 graduates. For a single randomly selected graduate, find the probability that her salary is between $156,692.00 and $161,395.00. For a simple random sample of 39 graduates, find the probability that the average salary is between $156,692.00 and $161,395.00. Is the assumption of normal necessary? Yes, or No.
