Suppose we wish to know whether the effect of SAT on gpa differs by gender.We create an interaction term. SAT_Fem=SAT*Female.We include it in Model 5, with coefficients found below.

. regress cumgpa female white fem_white sat sat_fem

Two non-white females originally took the SAT and got the same score.One of them then studied hard and improved her score by 100.What is the predicted difference in cumgpa between the two females?
