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. What will the GPA be if the number of hours spent studying is 30 the IQ is 108, and the high school average is 82?

• A) 3.1446
• B) 2.9306
• C) 0.428
