A question of medical interest is whether jogging leads to a reduction in blood pressure. To learn about this question, eight non-jogging volunteers have agreed to begin a 1-month jogging program. At the end of the month their blood pressure was determined and compared with the earlier values, the data in the table below. Use a significance level of 0.01 to test the hypothesis that 1-month jogging will tend to reduce the blood pressure. # Blood Pressure Before Blood Pressure After 1 134 130 2 122 120 3 118 123 4 130 127 5 144 138 6 125 121 7 127 132 8 133 134
