samples are independe study was body tempera random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. State th conclusion for the test. Use a 0.01 significance level to test the claim that men have a higher mean body temperature than women. μ n FIX X S Men H1 11 97.66°F 0.75°F Women H₂ 59 97.22°F 0.68°F 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. 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 C. Reject the null hypothesis. There is sufficient evidence to support the claim that men have a higher mean body temperature than women. O D. Fail to reject the null hypothesis.
