Question

Assume a significance level of alpha equals 0.1 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 17 bpm. The hypothesis test results in a​ P-value of 0.2678

a. State a conclusion about the null hypothesis.​ (Reject Upper H 0 or fail to reject Upper H 0​.) Choose the correct answer below.

A. Reject Upper H 0 because the​ P-value is less than or equal to a

B.Reject Upper H 0 because the​ P-value is greater than a

C.Fail to reject Upper H 0 because the​ P-value is less than or equal to a

D.Fail to reject Upper H 0 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?

A.There is sufficient evidence to support the claim that the standard deviation of pulse rates of the group of adult males is more than 17 bpm.

B.The standard deviation of pulse rates of the group of adult males is less than or equal to 17 bpm.

C.The standard deviation of pulse rates of the group of adult males is more than 17 bpm.

D. 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 17 bpm.
