A professor obtains SAT scores and freshman grade point averages (GPAs) for a group of n = 15 college students. The SAT scores have a mean of M-580 with SS - 22,400, and the GPAs have a mean of 3.10 with SS = 1.26, and SP = 84. Find the regression equation for predicting GPA from SAT scores. (Use five decimal places for the slope.) What percentage of the variance in GPAs is accounted for by the regression equation? (Compute...
