An advertising company is interested in determining if there is a difference in the mean sales that will be generated for a soft drink company based on which shelf the soft drinks are located. There are four possible shelf levels. The ad company wants to control for store size. The following data reflect the sales for one week at each combination of shelf level and store size.

	Level 1	Level 2	Level 3	Level 4
Small Store	300	200	500	200
Medium Store	400	180	600	200
Large Store	600	300	900	400

Based on the experimental design, the managers should conclude that they were justified in blocking on store size if they test using a 0.05 level of significance.
