Which of the following statements is false? ? a. the impacts of estimation errors and forecasting risks are small when npvs are large and positive. b. under intense competition, positive npv projects are as common as negative npv projects. c. scenario analysis determine the reasonable range of expectations for a project's outcome. d. sensitivity analysis identify the variable within a project that presents the greatest forecasting risk.

Total marketing effort is a term used to describe the critical decision factors that affect demand: price, advertising, distribution, and product quality. define the variable x to represent total marketing effort. a typical model that is used to predict demand as a function of total marketing effort is based on the power function: d = axb suppose that a is a positive number. different model forms result from varying the constant b. sketch the graphs of this model for b = 0, b = 1, 0< b< 1, b< 0, and b> 1. (we encourage you to use excel to do this.) what does each model tell you about the relationship between demand and marketing effort? what assumptions are implied? are they reasonable? how would you go about selecting the appropriate model?
