The crime prevention strategy used in the movie Minority Report was based on reports of future crimes given to investigators by psychics who could predict the future in order to prevent the crimes from occurring. The future perpetrators had the required intent to commit a crime, but all of the people arrested in the film for future actions that they have not committed should not be charged with a crime because this essential element is missing .

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?
