The fоllоwing estimаted regressiоn equаtion hаs been proposed to predict sales at a fast food outlet. y = 18 - 2x1 + 7x2 + 15x3 where x1 = the number of competitors within 1 mile x2 = the population within 1 mile (in 1000s) x3 = 1 if drive-up windows are present; 0 otherwise = estimated sales (in $1000s) What is the interpretation of 15 (the coefficient of x3) in the regression equation? Be specific within the context of the problem.
