Question 10-50<\/p>\n
A golf club manufacturer is trying to determine how the price of a set of clubs affects the demand for clubs. The file P10_50.xlsx contains the price of a set of clubs and the monthly sales.<\/p>\n
a) Assume the only factor influencing monthly sales is price. Fit the following three curves to these data: linear (Y = a + bX), exponential (Y = abX), and multiplicative (Y = aXb). Which equation fits the data best?<\/p>\n
b) Interpret your best-fitting equation.<\/p>\n
c) Using the best-fitting equation, predict sales during a month in which the price is $470.<\/p>\n
Question 12-64<\/p>\n
Let Yt be the sales during month t (in thousands of dollars) for a photography studio, and let Pt be the price charged for portraits during month t. The data are in the file P11_45.xlsx. Use regression to fit the following model to these data:<\/p>\n
Yt = a + b1Yt\u22121 + b2Pt + et<\/p>\n
This equation indicates that last month\u2019s sales and the current month\u2019s price are explanatory variables. The last term, et, is an error term. a. If the price of a portrait during month 21 is $10,<\/p>\n
what would you predict for sales in month 21? b. Does there appear to be a problem with<\/p>\n
autocorrelation of the residuals?<\/p>\n
