Question: The makers of the Plus 20 Hard card, a plug-in hard disk unit on a PC board, have recently done a marketing research study in which they asked two independently selected groups to rate the Hard card on a scale of 1 to 100, with 100 being perfect satisfaction. The first group consisted of professional computer programmers. The second group consisted of home computer users. The company hoped to be able to say that the product would receive the same median ranking from each group. The following summary data were recorded:

Professionals                    Home Users

n = 10                            n = 8

Sum of ranks = 92            Sum of ranks = 79

Based on these data, what should the company conclude? Test at the α = 0.02 level.
