Question

The retailing manager of a supermarket chain wants to determine whether product location has any effect on the sale of pet toys. Three different aisle locations are 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. At the end of a one-month trial period, the sales volumes (in thousands of dollars) of the product in each store were as follows. At the 0.05 level of significance, is there evidence of a difference in the mean sales among the various aisle locations?

Explanation / Answer

Since the above table the calculated F-value = 14.10 is greater than F-cric value =3.68, also P-value 0.00 which is less than 0.05, hence we can conclude that their is a significant difference in the mean sales among the various aisle location at alpha =0.05.

Front Middle Rear 8.6 3.2 4.6 7.2 2.4 6 5.4 2 4 6.2 1.4 2.8 5 1.8 2.2 4 1.6 2.8
