A medicalresearcher decides to test her belief that walking briskly for at least half anhour a day has the effect of lowering blood pressure. She conducts a smallpilot study. If results from it are supportive, she will apply for funding for alarger study. She randomly samples three of her patients who have high bloodpressure. She measures their systolic blood pressure initially and then again amonth later after they participate in her exercise program. The table showsthe results.Subject13Before After150130165140135120Do a significance testing with a 95% confidence level.
