Male BMI Female BMI
Given in the table are the BMI statistics for random samples of men and women. 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 0.01 significance level for both parts to test the claim that males and females have the same mean boly mass index
(BMI) as follows.

(Round to three decimal places as needed.)
The test statistic, t, is
(Round to three decimal places as needed.)
State the conclusion for the test.
O A. Reject the null hypothesis. There is sufficient evidence to warrant rejection of the claim that men and women have the same mean BMI.
O B. Fail to reject the null hypothesis. There is sufficient evidence to warrant rejection of the claim that men and women have the same mean BMI.
ontents
O C. Fail to reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that men and women have the same mean BMI.
Success
O D. Reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that men and women have the same mean BMI.
