The standard deviation of these scores is 35. A special preparation course claims that the mean SAT score, u, of its graduates is greater than 538. An independent researcher tests this by taking a random sample of 80 students who completed the course; the mean SAT score in mathematics for the sample was 542. At the 0.01 level of significance, can we conclude that the population mean SAT score for graduates of the course is greater than 5387 Assume that the population standard deviation of the scores of course graduates is also 35. Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below.
