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 8 adults. The following table presents the results. Systolic Diastolic 125 85 108 85 103 78 114 78 119 67 118 88 131 75 116 71 Send data to Excel The least-squares regression line y = bo +b,x= 89.6478 – 0.0966x and E (x-x)*= 551.5000 are known for this data. Use the critical value method to test H, : B, = 0 versus H, : B, < 0. Can you conclude that systolic blood pressure is useful in predicting diastolic blood pressure? Use the a = 0.05 level of significance. Part: 0/4 Part 1 of 4 Find the critical value(s). Round the answer to three decimal places. If there is more than one critical value, separate them with commas. Critical value(s):
