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 selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. a. Test the claim that the two samples are from populations with the same mean. ( use a 0.05 significance level to test the claim that men have a higher mean body temperature than women) What are the null and alternative hypotheses? What is the test statistic, t? What is the P-value? State the conclusion for the test. b. Construct a confidence interval suitable for testing the claim that the two samples are from populations with the same mean.

Question
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 selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below.
a. Test the claim that the two samples are from populations with the same mean . ( use a 0.05 significance level to test the claim that men have a higher mean body temperature than women)
What are the null and alternative hypotheses?
What is the test statistic, t?
What is the P-value?
State the conclusion for the test.
b. Construct a confidence interval suitable for testing the claim that the two samples are from populations with the same mean.
