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 15.3 percent, and sat i was last at 13.5 percent." 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?
