In the following estimated model, Y is the expenditure on beers, X, is the expenditures on fried chickens, and M is a dummy variable indicating 1 for males, 0 for females. -0.6 +1.5M + 0.5X + 0.2MX Here, Student C uses a dummy variable F, instead of M for regression, where F, has the value 1 for females and 0 for males. That is, he estimates the following equation: Y B + BF+ B3X + B4FiX + ei Obtain the estimated values of B, B2, B3, and 4.
