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 naturally distributed populations, and not assume that the population standard deviations are equal. Use 0.01 significance level for both parts

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 naturally distributed populations, and not assume that the population standard deviations are equal. Use 0.01 significance level for both parts

State the conclusion for the test.
O A. Reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that men and women have the same mean BMI.
O B. Reject the null hypothesis. There is sufficient evidence to warrant rejection of the claim that men and women have the same mean BMI.
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.
O D. 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.
b. Construct a confidence interval suitable for testing the claim that males and females have the same mean BMI.
