A study was done on body temperature 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 . Use a 0.05 significance level for both parts.
Men: mean 1, n=11, x bar= 97.55 degree F, s= 0.87 degree F.
Women: mean 2, n=59, x bar 97.44 degree F, s= 0.72 degree F
(a). 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?
What is the P-value
State the conclusion
(b) construct a confidence interval for testing the claim that men have a higher mean body temperature than women.
Does the confidence interval support the conclusion found with the hypothesis test?
