Grade point average (GPA) is a function of IQ scores (X1) , hours spent studying each week (X2) , and
One's high school average (X3) . Suppose the regression equation is:
Y' = -6.9 + 0.055X1 + 0.107X2 + 0.0083X3.
The multiple standard error is 6.313 and R2 = 0.826.Assuming other independent variables are held
Constant, what effect on the GPA will there be if the numbers of hours spent studying per week
Increases from 32 to 36?

• A) 3.1446
• B) -0.824
• C) +0.428
