Assume a significance level of α=0.05 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 19 bpm. The hypothesis test results in a P-value of 0.3587. COMPLETE PARTS A & B A. State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0.) Choose the correct answer below. A. Reject H0 because the P-value is less than or equal to α. B. Fail to reject H0 because the P-value is greater than α. C. Fail to reject H0 because the P-value is less than or equal to α. D. Reject H0 because the P-value is greater than α. B. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion? A.The standard deviation of pulse rates of the group of adult males is more than 19 bpm.

Assume a significance level of α=0.05 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 19 bpm. The hypothesis test results in a P-value of 0.3587.

COMPLETE PARTS A & B

A. State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0.)

Choose the correct answer below.

A. Reject H0 because the P-value is less than or equal to α.

B. Fail to reject H0 because the P-value is greater than α.

C. Fail to reject H0 because the P-value is less than or equal to α.

D. Reject H0 because the P-value is greater than α.

B. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion?

A.The standard deviation of pulse rates of the group of adult males is more than 19 bpm.

B.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 19 bpm.

C.The standard deviation of pulse rates of the group of adult males is less than or equal to 19 bpm.

D.There is sufficient evidence to support the claim that the standard deviation of pulse rates of the group of adult males is more than 19 bpm.
