A recent pilot study tested whether walking daily improved systolic blood pressure. For the three subjects in the study, their resting systolic blood pressure was measured Subject Before After 1 at the beginning of the study and again after participating in a walking program for 3 weeks. The table shows the results. Use the technology output to answer parts a through c. 155 2 125 Click the icon to view the technology output. 3 125 a. State the hypotheses to which the reported P-value refers. Let Hd be the population mean of the differences d = Before After. Choose the correct answer below. A. Ho: Hd = 0 and Ha: Hd > 0 OB. Ho: Hd #0 and Ha: Hd = 0 OC. Ho: Hd = 0 and Ha: Hd <0 D. Ho: Hd = 0 and Ha: Hd #0 b. Explain how to interpret the P-value. Using a significance level of 0.05, does the exercise program seem beneficial to lowering blood pressure? A. Since the P-value is greater than or equal to 0.05, there is sufficient evidence to suggest that the exercise program lowers blood pressure. OB. Since the P-value is less than 0.05, there is insufficient evidence to suggest that the exercise program lowers blood pressure. c. Since the P-value is greater than or equal to 0.05, there is insufficient evidence to suggest that the exercise program lowers blood pressure. OD. Since the P-value than 0.05, there is sufficient evidence to suggest that program blood pressure. c. What are the assumptions on which this analysis is based? A. The experiment is randomized and the subjects are dependent. OB. The experiment is randomized and there is a normal population distribution of difference scores. OC. The experiment is randomized and the subjects are independent. experiment in randomized and there is a normal complo distribution of difference.coor 150 125 115
