ONLY ANSWER PARTS F AND G SHOWN IN THE SECOND PICTURE. PREVIOUS PARTS (A-E) HAVE ALREADY BEEN ASKED SEPERATELY

IConsider the following multiple linear regression model and the Excel print out of its regression results: Beer = Bo + BIEDUC + B2AGE + BAGE? + BAGENDER + BERACE+ BEGENDER*RACE+ E, where Beer is monthly beer consumption (ounces), EDUC is years of education. We have 2 qualitative variables: gender and race. Gender takes 2 values, GEN=1 if the person is male and GEN=0 for females. The variable race also takes 2 values, RACE=1 if the person is white and RACE=0 if the person is not white.
