Question

3. A study done on body temperatures of men and women. The results are shown below: Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Use a 0.05 significance level To test the claim that men have a higher mean body temperature than women. μ1 n1 = 11 X1 = 97.57 S1 = 0.78 degree F degree F μ2 n2 = 59 X2 = 97.43 degree F S2 = 0.61 degree F a. Identify the null hypotheses and alternate hypotheses, addresses the original claim. Ho: H1: b. Find the test statistics equation and value. c. Find the P value for this hypothesis test. c. State the conclusion about Ho and H1. Why do we accept/reject Ho and accept/reject H1? Construct a confidence interval suitable for testing the claim that men have a higher mean body temperature than women. (Round to three decimal places as needed.) (do not need to use the formula)
