Many television viewers express doubts about the validity of certain commercials. In an attempt to answer their critics, the Timex Corporation wishes to estimate the proportion of consumers who believe what is shown in Timex television commercials. Let p represent the true proportion of consumers who believe what is shown in Timex commercials. If Timex has no prior information regarding the true value of p, how many consumers should be included in their sample so that they will be 80% confident that their estimate is within .03 of the true value of p (Margin of error .03)
