Business Weekly conducted a survey of graduates from several top MBA programs. On the basis of the survey, assume the mean annual salary for graduates 10 years after graduation is $141,000. Assume the standard deviation is $42,000. Suppose you take a simple random sample of 16 graduates. Round all answers to four decimal places if necessary. • What is the standard deviation of distribution of X? • What is the standard deviation of X? • For a single randomly selected graduate, find the probability that her salary is between $142,750 and $149,200. • For a simple random sample of 16 graduates, find the probability that the average salary is between $142,750 and $149,200.
