Question
A store wants to determine whether product location has an effect on the sales of a toy. A random sample of 18 stores is​ selected, with six stores randomly assigned to each of three aisle locations. The sales volume at the end of a trial period is shown in the accompanying table. At the
0.01
level of​ significance, is there evidence of a significant difference between the median sales of the various aisle​ locations?
