Chapter 5
1.  The forecasting staff for the Prizer Corporation has developed a model to predict sales of its air-cushioned-ride snowmobiles. The model specifies that sales S vary jointly with disposable personal income Y and the population between ages 15 and 40, Z, and inversely with the price of the snowmoblies P. Based on past data, the best estimate of this relationship is *YZ/P where k has been estimated (with past data) to equal 100.
a. If Y = \$11,000, Z = \$1,200, and P = \$20,000, what value would you predict for S ?
b. What happens if P is reduced to \$17,500?
c. How would you go about developing a value for k?
d. What are the potential weaknesses of  his model?
