What do you guys think it is?

Definition: A completely Randomized Design is one
in which each experimental unit is randomly assigned to a treatment.
A treatment is any combination of the values of the factors.

Examples: A fast food franchise is test marketing 3 new menu items. To find out if they
the same popularity, 18 franchisee restaurants are randomly chosen for participation in the study. In accordance with the completely randomized design, 6 of the restaurants are randomly chosen to test market the first new menu item, another 6 for the second menu item, and the remaining 6 for the last menu item.
Problem: Suppose the following table represents the sales figures of the 3 new menu
items in the 18 restaurants after a week of test marketing. At .05 level of significance, test whether the mean sales volume for the 3 new menu items are all equal.
Item1 Item2 Item3 22 52 16 42 33 24 44 8 19 52 47 18 45 43 34 37 32 39
