Assume a significance level of a = 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 13 bpm. The hypothesis test results in a P-value of 0.2597. a. State a conclusion about the null hypothesis. (Reject Ho or fail to reject Ho.) Choose the correct answer below. A. Fail to reject H, because the P-value is less than or equal to a. B. Reject Ho because the P-value is less than or equal to a. C. Reject H, because the P-value is greater than a. D. Fail to reject H, because the P-value is greater than o. 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 less than or equal to 13 bpm. B. The standard deviation of pulse rates of the group of adult males is more than 13 bpm. C. 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 13 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 13 bpm.
