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 68 bpm. The hypothesis test results in a P-value of 0.0046.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 a.OB. Fail to reject Ho because the P-value is less than or equal to a.OC. Reject Ho because the P-value is greater than a.OD. Fail to reject Ho because the P-value is greater than a.NXb. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion?OA. 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 68 bpm.OB. 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.OC. The mean pulse rate (in beats per minute) of the group of adult males is not 68 bpm.OD.

The commercial for the new Meat Man Barbecue claims that it takes 14 minutes for assembly. A consumer advocate thinks that the assembly time is lower than 14 minutes. The advocate surveyed 12 randomly selected people who purchased the Meat Man Barbecue and found that their average time was 13.5 minutes. The standard deviation for this survey group was 2.1 minutes. What can be concluded at the the a = 0.01 level of significance level of significance? You may assume the data are normally distributed.
