1. A researcher at a private college in Oregon was interested in relating cumulative GPA (CGPA) on graduation from the college to SAT math scores. For last year's graduating class she computed a correlation of r = 0.43. How much of the variability in CGPA can be associated with differences in SAT math scores?
3. For each of the two scatterplots below, I have provided the value for the coefficient of determination. In each case, please compute the value for the correlation coefficient.
