Assume a significance level of a = 0.01 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 14 bpm. The hypothesis test results in a P-value of 0.3989. ..... 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. O B. Fail to reject Ho because the P-value is greater than a. OC. Rejeco because the P-value is greater than a. O D. Fail to 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? O A. 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 14 bpm. O B. There is sufficient evidence to support the claim that the standard deviation of pulse rates of the group of adult males is more than 14 bpm. O C. The standard deviation of pulse rates of the group of adult males is more than 14 bpm. O D. The standard deviation of pulse rates of the group of adult males is less than or equal to 14 bpm.

Transcribed Image Text:Assume a significance level of a = 0.01 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 14 bpm. The hypothesis test results in a P-value of 0.3989.
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.
O B. Fail to reject Ho because the P-value is greater than a.
O C. Rejecdo because the P-value is greater than a.
O 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 not sufficient evidence to support the claim that the standard deviation of pulse rates of the group of adult males is more than 14 bpm.
O B. There is sufficient evidence to support the claim that the standard deviation of pulse rates of the group of adult males is more than 14 bpm.
O C. The standard deviation of pulse rates of the group of adult males is more than 14 bpm.
