I WILL RATE An article included a summary of findings regarding the use of SAT I scores, SAT II scores, and high school grade point average (GPA) to predict first-year college GPA. The article states that "among these, SAT II scores are the best predictor, explaining 17 percent of the variance in first-year college grades. GPA was second at 15.7 percent, and SAT I was last at 13.8 percent." (a) If the data from this study were used to fit a least squares line with y = first-year college GPA and x = high school GPA, what would the value of r2 have been? r2 = (b) The article stated that SAT II was the best predictor of first-year college grades. Do you think that predictions based on a least-squares line with y = first-year college GPA and x = SAT II score would be very accurate? Explain why or why not. Yes. The r2 value for y = first year college GPA and x = SAT II score is positive which suggests an approximate linear relationship between the two variables may be present. No. The r2 value for y = first year college GPA and x = SAT II score is small which does not suggest an approximate linear relationship between the two variables may be present. Yes. The r2 value for y = first year college GPA and x = SAT II score is small which suggests an approximate linear relationship between the two variables may be present. No. The r2 value for y = first year college GPA and x = SAT II score is large which does not suggest an approximate linear relationship between the two variables may be present. Yes. The r2 value for y = first year college GPA and x = SAT II score is large which suggests an approximate linear relationship between the two variables may be present
