1. Floor Polish To see whether a new floor polish A was superior to those produced by four competitors, B, C, D, and E, a manufacturer asked a sample of 100 housekeepers to view five identical patches of flooring that had received the five polishes. Each indicated the patch that he or she considered superior in appearance, with the results shown in the table.

Do these data present sufficient evidence to indicate a preference for one or more of the polished patches of floor over the others? If one were to reject the hypothesis of no preference for this experiment, would this imply that polish A is superior to the others?
Can you suggest a better way of conducting the experiment?
