Question

Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal.

Refer to the accompanying data set. Use a

0.01

significance level to test the claim that women and men have the same mean diastolic blood pressure.

Let u, be the mean diastolic blood pressure for women and let u, be the mean diastolic blood pressure for men. What are the null and alternative hypotheses?
O A. Ho: H1 = H2
H;: H,> H2
O B. Ho: H1 <H2
H,: H1 = H2
O D. Ho: H1= H2
O C. Họi H1H2
H,: H1 =H2
Calculate the test statistic.
t3=
(Round to two decimal places as needed.)
Find the P-value.
P-value =
(Round to three decimal places as needed.)
Make a conclusion about the null hypothesis and a final conclusion that addresses the original claim.
V Ho. There
sufficient evidence to warrant rejection of the claim that women and men have the same mean diastolic blood pressure.
