One of the leading washer and dryer manufacturers has estimated the following demand equation based on the data from its 47 branch offices and dealerships across the country:

Q = 12,000 - 20P + 120A + 15P_C- 100A_C+ 80I - 20P_D

(6400) (8) (50) (8) (46) (35) (11)

R² = 0.72 F = 20.15

The variables and their assumed values are

Q = Quantity

P = Price of basic model = 500

A =Advertising expenditures = 50

P_C =Average price of the competitor's product = 600

A_C= competitor's advertising expenditures = 30

I = per capita income = 75

P_D= price of the dryer = 600

For each variable below, indicate whether it is or not statistically significant, based of the T-test.
