Business Weekly conducted a survey of graduates from 30 top MBA programs. On the basis of the survey, assume the mean annual salary for graduates 10 years after graduation is 167000 dollars. Assume the standard deviation is 34000 dollars. Suppose you take a simple random sample of 89 graduates. Find the probability that a single randomly selected policy has a mean value between 160512.8 and 180695.2 dollars. P(160512.8 < X < 180695.2) = Find the probability that a random sample of size n = 89 has a mean value between 160512.8 and 180695.2 dollars.
