Q) The following is the multiple regression equation, (standard errors in parentheses.)

Q = 8,400 - 10 P_x + 5 A + 4 P_y + 0.05 I

_{(2.29)(1.36)(1.75)(0.15)}

R2= 0.65N = 120F = 35.25

Standard error of estimate = 34.3Q = Quantity demanded

P_x = Price = 1,000 A = Advertising expenditures, in thousands = 40

P_y= price of competitor's good = 800I = average monthly income = 4,000
