This test: 100 point(s) possible Question 19 of 20 Submit test This question: 5 point(s) possible Men Women H1 H2 A study was done on body temperatures of men and women. The results are shown in the table. Assume that the two samples are independent simple random samples n 11 59 selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. X 97.53 F 97.36 F 0.91 F 0.68 F a. Use a 0.01 significance level to test the claim that men have a higher mean body temperature than women. What are the null and alternative hypotheses? O A. HO: H1 2 H2 OB. HO: H1 # H2 H1 : Hy H2 The test statistic, t, is (Round to two decimal places as needed.) The P-value is . (Round to three decimal places as needed.) State the conclusion for the test. O A. Reject the null hypothesis. There is not sufficient evidence to support the claim that men have a higher mean body temperature than women. O B. Reject the null hypothesis. There is sufficient evidence to support the claim that men have a higher mean body temperature than women. C. Fail to reject the null hypothesis. There is not sufficient evidence to support the claim that men have a higher mean body temperature than women. O D. Fail to reject the null hypothesis. There is sufficient evidence to support the claim that men have a higher mean body temperature than women. b. Construct a confidence interval suitable for testing the claim that men have a higher mean body temperature than women.
