Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters, for a sample of 7 adults. The following table presents the results. Do people with higher diastolic pressure tend to have higher or lower systolic pressures? Systolic Diastolic 133 91 134 87 112 75 115 83 107 71 113 77 110 74 Send data to Excel The least-squares regression line y =bbx=6.1772+0.6247x and E (x-x) = 735.4286 are known for these data. Use the P-value method to test H:B,=0 versus H, :B, ± 0. Can you condlude that systolic blood pressure is useful in predicting diastolic blood pressure? Use the a=0.01 level of significance. Part: 0/4 Part 1 of 4 Compute the test statistic. Always roundt-score values to three decimals places.
