You decided to buy your friend an ice cream for lunch at your favorite upscale ice cream parlor about ten miles away from the office. It was wintertime, and you noticed for the first time just how many local ice cream restaurants and stands there were in your area. Funny, they were almost all closed during the winter months. Despite the cold weather you had to wait a couple minutes for a table to clear at the parlor. You mention to an employee that you must have hit a busy day, but they respond that it’s not unusually busy today. You start to think about the conversation you had earlier with the Sr. VP, and you wonder if he or you, or anyone at your client firm really understands the local market at all. You are not really sure if sales locally will be any different than in Southwestern markets. Show a design that reflects this line of thought. Show an experimental design, which includes, at a minimum: a) Indicate whether this is a one-tail or two-tail test, and why. Sketch the problem. b) State your hypotheses c) Identify the level of significance (with justification) d) State the ramifications of the two types of errors, specific to this business
