In order to create a behavioral profile of pleasure travelers, M. Bonn (Florida State University), L. Forr (Georgia Southern University), and A. Susskind (Cornell University) interviewed 5,026 pleasure travelers in the Tampa Bay region (Journal of Travel Research, May 1999). Two of the characteristics they investigated were the travelers' education level and their use of the Internet to seek travel information. The table below summarizes the results of the interviews. The researchers concluded that travelers who use the Internet to search for travel information are likely to be people who are college educated. Do you agree? Test using a = .05.
