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:

    Front Aisle Location: 8.6, 7.2, 5.4, 6.2, 5.0, 4.0

    Middle Aisle Location: 3.2, 2.4, 2.0, 1.4, 1.8, 1.6

    Rear Aisle Location: 4.6, 6.0, 4.0, 2.8, 2.2, 2.8

    a. At the 0.05 level of significance, is there evidence of a significant difference in mean sales among the various aisle locations?
    b. If appropriate, which aisle locations appear to differ significantly in mean sales?
    c. n/a
