26. The manager of the Ahumada Restaurant Chain wants to test the market for a new menu item: a grilled chicken sandwich with chipotle salsa. They are interested in both how to market the item and the right price to charge for it. She decides to offer the sandwich at 60 different restaurants in the chain, using two different descriptions on the menu. Half the restaurants' menus will emphasize "healthy eating" and half will emphasize "value." These two groups of restaurants will be further divided in three groups, each charging either a High, Medium, or Low price for the sandwich. After a month, they will measure what proportion of customers order the new sandwich. (a) Suppose the manager plans to conduct a completely randomized design. List the experimental units, factors, and treatments in this experimental design and explain your method of randomization.. Then Draw out the design.
