It Has Been Hypothesized That Overall Academic Success for Freshmen

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
