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. 3. 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. O.

Question 2, 10.4.50

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 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. Click the icon to view the technology output. a. State the hypotheses to which the reported P-value refers.
