It has been hypothesized that overall academic success for freshmen at college as measured by 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. How will a student's GPA be affected if an additional hour is spent studying each weeknight?
