Assume a significance level of a=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 70 bpm. The hypothesis test results in a P-value of 0.0851a. State a conclusion about the null hypothesis. (Reject Ho or fail to reject Ho) Choose the correct answer below.OA. Fail to reject Ho because the P-value is greater than a.OB. Reject Ho because the P-value is greater than a.O C. Fail to reject Ho because the P-value is less than or equal toO D. Reject Ho 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?OA. The mean pulse rate (in beats per minute) of the group of adult males is not 70 bpm.OB. The mean pulse rate (in beats per minute) of the group of adult males is 70 bpm.OC. 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 70 bpm.O D. 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 70 bpm.
