It Has Been Hypothesized That Overall Academic Success for Freshmen

question 127

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 is the predicted GPA for a student with an IQ of 108, 32 hours spent studying per week and a high school average of 82?

• A) 3.1446
• B) 2.9306
• C) 0.428
• D) 10.0446
• E) 13.1892
