Question

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 15 bpm. the hypothesis test results in a p - value of 0.3619. 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 not sufficient evidence to support the claim that the standard deviation of pulse rates of the group of adult males is more than 15 bpm. 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 15 bpm. c. the standard deviation of pulse rates of the group of adult males is less than or equal to 15 bpm. d. the standard deviation of pulse rates of the group of adult males is more than 15 bpm.

Explanation:

When the P - value ($0.3619$) is greater than the significance level ($\alpha = 0.05$), we fail to reject the null hypothesis. Failing to reject the null hypothesis means there is not enough evidence to support the alternative hypothesis (the original claim in this case).

Answer:

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 15 bpm.
