It has been hypothesized that overall academic success for college freshmen as measured by grade point average 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 (this is Y hat)=6.9+0.055x1 (the 1 is subscripted)+0.107x2 ( the 2 is subscripted)+0.0853X3 (the 3 is subscripted). The multiple standard error is 6.313 and R^2=0.826.
A. What is the predicted GPA for a student with a IQ of 108, 32 hours spent studying per week and a high school average of 82?
B. Which independent variable has the smallest affect on GPA?
C. For which independent variable does a unit change have the greatest effect on the GPA?
