How many units can sony expect to sell in a month using the


  • Forecasting:

 Suppose you are given the following regression equation for Sony's laptop computers (standard errors in parentheses.)

                        Q =    8,400  - 10 P +  5 A +  4 Px +   0.05 I

                                  (1,732)  (2.29)   (1.36)   (1.75)  ( 0.15)

R2 = 0.65

N = 120

F = 35.25

Standard error of estimate = 34.3

Q = Quantity demanded

P = Price of Sony Laptop computers = $1,000

A = monthly advertising expenditures (in thousands) = 40

PX = price of a related good = $800

I = average monthly income of buyers = $4,000
