**Context: Hypothesis Testing in Statistics**
**Assume a significance level of \( \alpha = 0.1 \) and use the given information to complete parts (a) and (b) below.**
**Original Claim**: The mean pulse rate (in beats per minute) of a certain group of adult males is 76 bpm. The hypothesis test results in a P-value of 0.0047.
**a. State a conclusion about the null hypothesis. (Reject \( H_0 \), or fail to reject \( H_0 \).) Choose the correct answer below:**
- A. Reject \( H_0 \) because the P-value is greater than \( \alpha \).
- B. Reject \( H_0 \) because the P-value is less than or equal to \( \alpha \).
- C. Fail to reject \( H_0 \) because the P-value is less than or equal to \( \alpha \).
- D. Fail to reject \( H_0 \) because the P-value is greater than \( \alpha \).
**Explanation:**
In hypothesis testing, the P-value is the probability of observing the test results under the null hypothesis. If the P-value is less than or equal to the significance level \( \alpha \), we reject the null hypothesis. Given \( \alpha = 0.1 \) and P-value = 0.0047, since 0.0047 < 0.1, we reject \( H_0 \).
**Correct Answer**: B. Reject \( H_0 \) because the P-value is less than or equal to \( \alpha \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5ca5a78a-5e75-4b40-ba71-d05535be357f%2Ffdd15d30-5ab3-4ab6-ac10-6e2147203e4e%2F2hzktz8_processed.jpeg&w=3840&q=75)
