Multiple Choice

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. For which independent variable does a unit change have the least effect on GPA?

• A) IQ scores (X₁)
• B) hours spent studying each week (X₂)
• C) high school average (X₃)
