A random sample of 18 stores is selected with 6 storesrandomly assigned to each aisle location. The size of the displayarea and price of the product are constant for all stores. At theend of a 1-month trial period, the sales volumes (in thousands ofdollars) of the product in each store were as follows:

8.8 3.4 4.6
7.4 2.6 6.0
5.6 2.2 4.0
6.4 1.6 2.8
5.2 2.0 2.2
4.2 1.8 2.8
