Management proposed the following regression model to predict sales at a fast-food outlet. y = Bo + B1X1 + B2X2+ B3X3+ E where X = number of competitors within one mile X2 = population within one mile (1,000s) J1 if drive-up window present X3 = 0 otherwise y = sales ($1,000s). The following estimated regression equation was developed after 20 outlets were surveyed. ŷ = 10.5 - 4.2x, + 6.8x2 + 15.9x3 (a) What is the expected amount of sales (in dollars) attributable to the drive-up window? $ (b) Predict sales (in dollars) for a store with three competitors within one mile, a population of 8,000 within one mile, and a drive-up window 24 (c) Predict sales (in dollars) for a store with one competitor within one mile, a population of 3,000 within one mile, and no drive-up window.
