Question
A study was done on body temperatures 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. Complete parts (a) and (b) below.
a. Use a 0.01 significance level to test the claim that men have a higher mean body temperature than women.
What are the null and alternative hypotheses?
O B. Ho: H1 = H2
O A. Ho: H12 H2
H: H1 <H2
H1: H1 # H2
O D. Ho: H1 =H2
H1:H1> H2
OC. Ho: H1#H2
H1:41<H2
The test statistic, t, is
(Round to two decimal places as needed.)
The P-value is
(Round to three decimal places as needed.)
Stoto the conclusion for the test.
