A doctor is estimating the blood pressure (mmHg) ofhis patient who is 36 years of age and weighs 135 pounds.

Using the multiple regression model which was determined in his previous analysis:

BloPre = 30.9941 + 0.8614 Age + 0.3349 Weight.

a) Find the blood pressure reading that this model estimates.

b) If the patient’s actual blood pressure is 110 mmHg, find the residual corresponding to this patient’s blood pressure.

c) What does that residual say about this measurement of blood pressure?
