Question

Assume a significance level of -O 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 bpm. The hypothesis test results in a Pvalue of 0.3426 a. State a conclusion about the null hypothesis. (Reject Ho or fail to reject Ho) Choose the correct answer below 0 A. Fail to reject Ho because the P-value is less than or equal to B. Fail to reject Ho because the P-value is greater than C. Reject Ho because the P-value is less than or equal to 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 B. The standard deviation of pulse rates of the group of adult males is less than or equal to 14 bpm C. The standard deviation of pulse rates of the group of adult males is more than 14 bpm 0 D There is not sufficient evidence to support the claim that the standard deviation of ulse rates of the group of adult males is more than 14 m

Explanation / Answer

B. If the p-value is more than 0.05, we fail to reject the null hypothesis that there's no difference between the means and conclude that a significant difference does exist.

b) Option D.
