Question

A study was done on body temperatures of men an d 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. Use a 0.01 significance level for both parts. The P-value is .153. (Round to three decimal places as needed.) State the conclusion for the test. A. Reject the null hypothesis. There is sufficient evidence to support the claim that men have a higher mean body temperature than women. B. Reject the null hypothesis. There is not sufficient evidence to support the claim that men have a higher mean body temperature than women. C. Fail to reject the null hypothesis. There is not sufficient evidence to support the claim that men have a higher mean body temperature than women. D. Fail to reject the null hypothesis. There is sufficient evidence to support the claim that men have a higher mean body temperature than women. Construct a confidence interval suitable for testing the claim that men have a higher mean body temperature than women.

Explanation / Answer

From following results

p-value=0.322

99% confidence interval= (-0.509, 1.029)

Two-Sample T-Test and CI

Sample N Mean StDev SE Mean

1 11 97.680 0.790 0.24

2 59 97.420 0.630 0.082

Difference = (1) - (2)

Estimate for difference: 0.260

99% CI for difference: (-0.509, 1.029)

T-Test of difference = 0 (vs ): T-Value = 1.03 P-Value = 0.322 DF = 12
