A subscription service stated that preference for different national magazines is independent of the geographical location of the subscribers. A survey was conducted in which 300 persons randomly selected from two areas were given a choice of three different magazines. Each person expressed their favorite. The following results were obtained: Region Magazine A Magazine B Magazine C New England 75 50 175 Middle Atlantic 120 85 95 The critical value of chi square obtained from the table for a 5%...
