Answer: FALSE Diff: 2Page Ref: 124-127 Main Heading: Marketing Example Key words: marketing problem, media selection 19) In a media selection problem, instead of having an objective of maximizing profit or minimizing cost, generally the objective is to maximize the audience exposure. Answer: TRUE Diff: 2Page Ref: 124-127 Main Heading: Marketing Example Key words: marketing problem, media selection 20) Linear programming model of a media selection problem is used to determine the relative value of each advertising media. Answer: FALSE Diff: 3Page Ref: 124-127 Main Heading: Marketing Example Key words: marketing problem, media selection 1) In a media selection problem, maximization of audience exposure may not result in maximization of total profit.
