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) = 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.
