Suppose you are tasked with studying the effect of class size on test scores for high school students. You collect data on class size and test scores from 100 high school classes. You then run an OLS regression of test scores on class size. The results for the intercept and slope coefficient on class size are 520.4 and -5.82, respectively with an R-Squared of 0.08. If a class goes from a class size of 19 students to a class size of 23 students, what do these results predict will be the change in test scores? 102.54 a. b, 23.28 28.65 C. d. None of these 19.89 e.
