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.

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.
