Extracted text: Assume a significance level of a = 0.05 and use the given information to complete parts (a) and (b) below. Original claim: The standard deviation of pulse rates of a certain group of adult males is more than 13 bpm. The hypothesis test results in a P-value of 0.2162. a. State a conclusion about the null hypothesis. (Reject H, or fail to reject Ho:) Choose the correct answer below. O A. Fail to reject Ho because the P-value is less than or equal to a. O B. Fail to reject H, because the P-value is greater than a. O C. Reject H, because the P-value is greater than a. O D. Reject H, because the P-value is less than or equal to a. b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion? A. There is sufficient evidence to support the claim that the standard deviation of pulse rates of the group of adult males is more than 13 bpm. B. There is not sufficient evidence to support the claim that the standard deviation of pulse rates of the group of adult males is more than 13 bpm. C. The standard deviation of pulse rates of the group of adult males is more than 13 bpm. D. The standard deviation of pulse rates of the group of adult males is less than or equal to 13 bpm.
