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 149000 dollars. Assume the standard deviation is 42000 dollars. Suppose you take a simple random sample of 80 graduates. Find the probability that a single randomly selected policy has a mean value between 130217 and 137260.6 dollars. P(130217 < X < 137260.6) = (Enter your answers as numbers accurate to 4 decimal places.) Find the probability that a random sample of size n=80n=80 has a mean value between 130217 and 137260.6 dollars. P(130217 < M < 137260.6) = (Enter your answers as numbers accurate to 4 decimal places.)
