A medical researcher wishes to see whether there is a relationship between a person’s age, cholesterol level, and systolic blood pressure. Eight people are randomly selected. The data is listed in the table. First, find the multiple regression equation. Next, determine the coefficient of determination. Then, use the regression equation to predict a person’s blood pressure reading if the person selected is 50 years old with a cholesterol reading of 220.   Age Cholesterol level Blood pressure Person 1 38 220 116 Person 2 41 225 120 Person 3 45 200 123 Person 4 48 190 131
