????

The mean SAT score in mathematics is 529. The standard deviation of these scores is 33. A special preparation course claims that the mean SAT score, μ, of its graduates is greater than 529. An independent researcher tests this by taking a random sample of 34 students who completed the course; the mean SAT score in mathematics for the sample was 533. Assume that the population is normally distributed. At the 0.10 level of significance, can we conclude that the population mean SAT score for graduates of the course is greater than 529? Assume that the population standard deviation of the scores of course graduates is also 33. Perform a one-ailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below.
