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 Item

NOW YOU KNOW!  Okay now go learn and stuff.  Bye.
