Yоu аre in chаrge оf аdvertising fоr Carl’s Camping Company. You want to air television ads, but you are unsure about which TV network to place ads on. At the end of last year Fox had a 25% market share, CBS 35%, ABC 22%, and NBC 18%. Advertising prices for each network are based on those numbers. Before deciding which network to advertise on, you wonder if viewing patterns have changed this year. In order to test this, you conduct a survey of 200 of your customers and note which network they watch most often. 46 viewers chose Fox, 60 chose CBS, 59 chose ABC, and 35 chose NBC. Question; Based on the table in your previous test (and remembering that advertising rates/prices are based on last year's viewing patterns), which network is likely to be the best "value" this year? Explain.
