In a study designed to predict blood cholesterol levels from amount of daily
saturated fat in grams (X1) and number of hours of daily exercise (X2), we
determine that the slope of X1 is 5, the slope of X2 is –4, and the y intercept is
130. If someone reports that they typically eat 10 grams of saturated fat daily and
exercise 1 hour daily, what would you predict for the person's cholesterol level?
