The retailing manager of a food chain wishes to determine whether productlocation has any effect on the sale of pet toys. Three different aisle locations are tobe considered: front, middle, and rear. A random sample of 18 stores is selectedwith 6 stores randomly assigned to each aisle location. The size of the displayarea and price of the product are constant for all stores. Ant the end of a 1-weektrial period, the sales volume (in thousands) of the product in each store was asfollows:Aisle LocationFrontMiddleRear8.62.04.67.23.22.85.42.46.04.01.82.25.01.42.86.21.64.0 2.
