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 152000 dollars. Assume the standard deviation is 31000 dollars. Suppose you take a simple random sample of 58 graduates. Find the probability that a single randomly selected policy has a mean value between 137753.3 and 150371.8 dollars. P(137753.3 < X< 150371.8) =| (Enter your answers as numbers accurate to 4 decimal places.) Find the probability that a random sample of size n = 58 has a mean value between 137753.3 and 150371.8 dollars. P(137753.3 < M < 150371.8) = (Enter your answers as numbers accurate to 4 decimal places.)
