Question

The retailing manager of a food chain wishes to determine whether product location has any effect on the sale of pet toys. Three different aisle locations are to be considered: front, middle, and rear. A random sample of 18 stores is selected with 6 stores randomly assigned to each aisle location. The size of the display area and price of the product are constant for all stores. Ant the end of a 1-week trial period, the sales volume (in thousands) of the product in each store was as follows:

Aisle Location

Front

Middle

Rear

8.6	2.0	4.6
7.2	3.2	2.8
5.4	2.4	6.0
4.0	1.8	2.2
5.0	1.4	2.8
6.2	1.6	4.0

At the .05 level of significance, is there evidence of a difference in average sales between the various aisle locations?

1. Yes, 14.1 > 3.68
2. No, 14.1 > 3.68
3. Yes, 36.4 > 22.4
4. Yes, 22.4 > 12.4
