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 $149,000. Assume the standard deviation is $33,000. Suppose you take a simple random sample of 6 graduates. Round all answers to four decimal places if necessary. What is the distribution of XX? XX ~ N(Correct,Correct) What is the distribution of ¯xx¯? ¯xx¯ ~ N(Correct,Correct) For a single randomly selected graduate, find the probability that her salary is between $154,692 and $171,228. Correct
