Hypothesis test for the population mean: Z test using p values V The mean SAT score in mathematics is 593. The standard deviation of these scores is 34. A special preparation course claims that the mean SAT score, u, of its graduates is greater than 593. An independent researcher tests this by taking a random sample of 60 students who completed the course; the mean SAT score in mathematics for the sample was 605. At the 0.01 level of significance, can we conclude that the population mean SAT score for graduates of the course is greater than 593? Assume that the population standard deviation of the scores of course graduates is also 34. 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. (If necessary, consult a list of formulas.) (a) State the null hypothesis Ho and the alternative hypothesis H1 . O H : 0 X S H :0 (b) Determine the type of test statistic to use. (Choose one) V 020 (c) Find the value of the test statistic. (Round to three or more decimal places.) * 00 (d) Find the p-value. (Round to three or more decimal places.)
