statistical methods

X To test the idea that walking can help lower blood pressure, a researcher looked at 8 randomly selected patients with high blood pressure. He measured their pressure before they participated in a walking program and a month after. The results obtained appear in the table below. Patient 1 2 3 4 5 6 7 8 Before 150 165 135 145 132 175 After 135 180 140 145 130 140 130 167 190 148 Is the walking program significantly effective in reducing a patient's blood pressure? Use a significance level of 5% (a = 0.05) To answer the question, you must: a) Calculate the mean W b) Calculate the standard deviation o'w c) State your test hypotheses HO and H1 d) Calculate your test statistic e) Perform the test f) Specify your decision rule and conclude
