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 14 bom. The hypothesis test results in a P-value of 0.2258. a. State a conclusion about the null hypothesis. (Reject Ho or fail to reject Ho.) Choose the correct answer below. O A. Fail to reject Ho because the P-value is less than or equal to a. O B. Reject Ho because the P-value is less than or equal to a. O C. Fail to reject Ho because the P-value is greater than a. O D. Reject Ho 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? O 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 14 bpm. O B. The standard deviation of pulse rates of the group of adult males is more than 14 bpm. O 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 14 bpm. O D. The standard deviation of pulse rates of the group of adult males is less than or equal to 14 bpm
