Question
![A study was conducted on body temperatures of men and women. The results are shown in the table below. The two samples are independent simple random samples selected from normally distributed populations without assuming equal standard deviations. Complete parts (a) and (b) below.
| | Men (μ₁) | Women (μ₂) |
|--------|----------|-------------|
| n | 11 | 59 |
| x̄ | 97.58°F | 97.35°F |
| s | 0.77°F | 0.64°F |
Use a 0.05 significance level to test the claim that men have a higher mean body temperature than women.
What are the null and alternative hypotheses?
A. \( H_0: μ_1 = μ_2 \)
\( H_1: μ_1 ≠ μ_2 \)
B. \( H_0: μ_1 ≥ μ_2 \)
\( H_1: μ_1 < μ_2 \)
C. \( H_0: μ_1 ≠ μ_2 \)
\( H_1: μ_1 < μ_2 \)
D. \( H_0: μ_1 = μ_2 \)
\( H_1: μ_1 > μ_2 \)
The correct choice is D.
The test statistic, t, is 0.93. (Round to two decimal places as needed.)
The P-value is [ ] (Round to three decimal places as needed.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F913862dd-ac5f-4038-847e-173683e2f265%2F08c51d9e-fe19-49d1-a7fc-95ce31bc4589%2Fdn34n7b_processed.jpeg&w=3840&q=75)
