Question

Assume a significance level of ?= 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 72 bpm. The hypothesis test results in a P-value of 0.0062. a. State a conclusion about the null hypothesis. (Reject Ho or fail to reject Ho) Choose the correct answer below. O A. Reject Ho because the P-value is less than or equal to ?. O B. Reject Ho because the P-value is greater than a OC. Fail to reject Ho because the P-value is greater than a D. Fail to reject Ho because the P-value is less than or equal to ?. b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion? O A. There is sufficient evidence to warrant rejection of the claim that the mean pulse rate (in beats per minute) of the group of adult males is 72 bpm. 0 B. There is not sufficient evidence to warrant rejection of the claim that the mean pulse rate (in beats per minute) of the group of adult males is 72 bpm. O C. The mean pulse rate (in beats per minute) of the group of adult males is 72 bpm O D. The mean pulse rate (in beats per minute) of the group of adult males is not 72 bpm.
