Good morning :) this is a test and I have 30 minutes to answer. No explanation needed

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 39000 dollars. Suppose you take a simple random sample of 66 graduates. Find the probability that a single randomly selected salary is at least 166000 dollars. P(X > 166000) = Find the probability that a sample of size n = 66 is randomly selected with a mean that is at least 166000 dollars. P(M > 166000) = Enter your answers as numbers accurate to 4 decimal places
