question 110

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. How will a student's GPA be affected if an additional hour is spent studying each weeknight?

• A) Increases by 0.535
• B) Decreases by 0.535
• C) Increases by 0.107
• D) Decreases by 0.107
• E) Increases by 0.0083
