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 6 adults. The following table presents the results. Systolic Diastolic 76 130 116 133 112 134 107 70 Part: 0/4 91 Part 1 of 4 75 87 Send data to Excel 71 The least-squares regression line y=bo +b, x=4.4261 +0.6058x and Σ (x-x)² = 690.0000 are known for this data. Use the critical value method to test Ho:B₁0 versus H₁ :B₁ >0. Can you conclude that systolic blood pressure is useful in predicting diastolic blood pressure? Use the a = 0.05 level of significance. 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): 0.0 X + 5
