Floor Polish A manufacturer of floor polishconducted a consumer preference experiment to seewhether a new floor polish A was superior to thoseproduced by four competitors, B, C, D, and E. Asample of 100 housekeepers viewed five patches offlooring that had received the five polishes, and eachindicated the patch that he or she considered superiorin appearance. The lighting, background, and so on were approximately the same for all five patches. Theresults of the survey are listed here:Polish AB C DEFrequency 27 17 15 22 19Do these data present sufficient evidence to indicate apreference for one or more of the polished patches offloor over the others? If one were to reject the hypothesisof no preference for this experiment, would this imply that polish A is superior to the others? Can yousuggest a better way of conducting the experiment?
