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.
a. Find the regression equation for predicting GPA from SAT scores.
c. Does the regression equation account for a significant portion of the variance in GPA? Use a=.05 to evaluate the F-ratio.© BrainMass Inc. brainmass.com June 3, 2020, 11:46 pm ad1c9bdddf
