Problem 2:
A manufacturer of computer workstations gathered average monthly sales figures from its 56 branch
offices and dealerships across the country and estimated the following demand for its product:
Q=+15,000-2.80P+150A+0.3P+0.35Pm+0.2Pc
(5,234) (1.29) (175) (0.12) (0.17) (0.13)
R²=0.68 SER 786 F=21.25
The variables and their assumed values are
P = Price of basic model = 7,000
Q==Quantity
A = Advertising expenditures (in thousands) = 52
P = Average price of a personal computer = 4,000
P.
Average price of a minicomputer = 15,000
Pe Average price of a leading competitor's workstation = 8,000
1. Compute the elasticities for each variable. On this basis, discuss the relative impact that each
variable has on the demand. What implications do these results have for the firm's marketing
and pricing policies?
2. Conduct a t-test for the statistical significance of each variable. In each case, state whether
a one-tail or two-tail test is required. What difference, if any, does it make to…
You are the manager of a large automobile dealership who wants to learn more about the effective-
ness of various discounts offered to customers over the past 14 months. Following are the average
negotiated prices for each month and the quantities sold of a basic model (adjusted for various
options) over this period of time.
1. Graph this information on a scatter plot. Estimate the demand equation. What do the
regression results indicate about the desirability of discounting the price? Explain.

difficulty in obtaining these additional data or incorporating them in the regression analysis?
