What are the null and alternative hypotheses?
OA. Ho: 1#H2
B. Ho: H1 2
H: H 2
C. Ho: H1 2H2
O D. Ho: H1 =H2
The test statistic, t, is 1.70. (Round to two decimal places as needed.)
The P-value is 0.092. (Round to three decimal places as needed.)
State the conclusion for the test.
A. 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.
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.
C. Reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that men and women have the same mean BMI.
D. 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.
(Round to three decimal places as needed.)
Does the confidence interval sunport the conclusion of the test?
