Original claim: The mean pulse rate (in beats per minute) of a certain group of adult males is 68 bpm. The hypothesis test results in a P-value of 0.0061. O A. Reject H, because the P-value is less than or equal to a. O B. Fail to reject H, because the P-value is less than or equal to a. O C. Fail to reject Ho because the P-value is greater than a. O D. Reject H, because the P-value is greater than a. 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 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 68 bpm. O B. The mean pulse rate (in beats per minute) of the group of adult males is not 68 bpm. O C.
