The marketing manager for Chipotle wants to make significant changes to the menu but first wants to test the potential impact of those changes on customers. The manager wants to run a true experiment involving four restaurants (two test and two control) and is using a satisfaction scale of 1 (low) to 5 (high) on the survey questions used to gauge customer reacting to the change. What would the experimental notation (remember the Xs and Os) look like for this scenario? Impute satisfaction scores (1 to 5) throughout the experimental model and explain the results.
