Question: Neighboring Troop Captain Marylou Shields, who heads District 14 of the Florida State Patrol, heard about Captain Mike’s study. While she says that “Mike and I are just friends,” some believe that there is more there than just meets the eye. Anyway getting back to the question and off of Marylou’s love life, she decides to use the same figures that “Mikey came up with” as a proxy for her district. What sample size should Marylou obtain so that the results are 95 percent certain that the estimate is off by not more than 0.03?
