Extracted text: Stonebuilt Concrete produces a specialty cement used in construction of roads. Stonebuilt is a price-setting firm and estimates the demand for its cement by the state department of transportation using a demand function in the nonlinear form: Q = a pb M pdr where Q= yards of cement demanded monthly, P= the price of Stonebuilt's cement per yard, M= state tax revenues per capita, and PR = the price of asphalt per yard. The manager at Stonebuilt transforms the nonlinear relation into a linear relation for estimation. The estimation results are presented below: F-RATIO 84.872 STANDARD P-VALUE ON F DEPENDENT VARIABLE: LNQ R-SQUARE OBSERVATIONS: 64 0.8093 0.0001 PARAMETER VARIABLE ESTIMATE ERROR T-RATIO P-VALUE INTERCEPT LNP 2.04 -2.16 3.38 0.0461 0.0357 0.0014 0.0439 8.20 4.01 -3.54 0.64287 0.7854 1.64 LNM 0.19 LNPR 0.38 2.07 If the price of asphalt (PR) decreases 15%, the estimated quantity of cement demanded will: Multiple Choice increase 5.2%. increase 11.8%. increase 1.18%. decrease 11.8%. decrease 5.2%.
