Question

Late-night talk show host David Lettermen made jokes about the name “Juke” for a Nissan motor vehicle. (It is kind of funny.) If you have been commissioned to conduct a survey of American drivers who see humor in the Juke name, how many American drivers must you survey? Assume that you want 97% confidence that your sample percentage is in error by no more than two percentage points. Is it OK to save money by conducting a telephone survey using only local phone numbers? Why or why not?
