The CEO of supermarket 'Taste' thinks of opening a branch in another shopping mall in Hong Kong. But before that he wants to study the consumer's preference for a particular store based on the variety of items sold in that store. He would compare his store with the leading supermarket chains like PNS and Welcome in a study in which 30 consumers participate. They are given a questionnaire which listed the variety of products sold in a particular departmental store for different item categories and asked them to rate their preference for that store which was measured on a 10 pointer scale, 1 (less preferred) and 10 (more preferred). These are then averaged for a single consumer and are given below in a table.

             PNS                        Welcome                     Taste

                3                              4                              6

                4                              6                              7

                6                              5                              4

                7                              4                              8

                8                              3                              9

                9                              6                              4

                6                              8                              5

                7                              6                              4

                6                              4                              7

                5                              8                              7
