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

Solution

Y = bo + b1 X1 + b2 X2
We have b0 = 130
b1 = 5
b2 = -4

person\'s cholesterol level ( Y ) = bo + 5 * saturated fat daily - 4 * exercises
= 130 + 5 * 10 - 4 * 1 = 130 + 50 - 4 = 176
