Extracted text: 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 180000 dollars. Assume the standard deviation is 39000 dollars. Suppose you take a simple random sample of 90 graduates. Find the probability that a single randomly selected salary exceeds 172000 dollars. P(X > 172000) = 90 is Find the probability that a sample of size n = randomly selected with a mean that exceeds 172000 dollars. P(M > 172000) = | 0.9744 %3D Enter your answers as numbers accurate to 4 decimal places.
