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.

The least-squares regression line y = b,+b,x 89.6478 – 0.0966x and E (x-x)
P-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 = 0.10 level of significance and the TI-84 calculator.
