A business school dean in Ohio wants to know if graduates who completed an internship during their undergraduate years earn more than business undergraduates who do not complete an internship while in college. Based on national survey from 1,500 business alumni with less than six years of work experience, they earn on average $50,970 with a standard deviation of $12,976. Business alumni from the Ohio school who completed internships on average earned $53,497. The dean wants you to be 96% confident in your results. a. State in statistical terms the null and alternative hypotheses. b. Determine the appropriate test statistic (z or t). c. Determine the critical value(s). d. Compute the test statistic. e. Make a decision on the hypotheses. (which hypothesis is correct?) f. Determine the p-value for the test statistic.
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 $138,000. Assume the standard deviation is $44,000. Suppose you take a simple random sample of 19 graduates. Round all answers to four decimal places if necessary. For a single randomly selected graduate, find the probability that her salary is between $141,759 and $156,006. For a simple random sample of 19 graduates, find the probability that the average salary is between $141,759 and $156,006.
