A lоcаl cоnsumer repоrter wаnts to compаre the average costs of grocery items purchased at three different supermarkets - Kroger, Giant Eagle, and Meier. Prices (in dollars) were recorded for a sample of 60 randomly selected grocery items at each of the three supermarkets. In order to reduce item-to-item variation, the prices were recorded for each item on the same day at each supermarket.
