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

------------------------------------------------------------------------------

cumgpa |Coef.Std. Err.tP>|t|[95% Conf. Interval]

Model 3 has SSE=204.72613 and Model 5 has SSE=179.51085.There are 635 observations.What test statistic will you calculate in order test the hypothesis that both SAT terms are jointly equal to 0?
