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 126 88 104 86 103 80 110 80 122 71 117 88 130 75 118 69 Send data to Excel The least-squares regression line y=b,+b,x= 101.5438 – 0.1885x and E (x- x) = 685.5000 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=0.01 level of significance.
