A local consumer reporter wants to compare the average costs of grocery items purchased at three different supermarkets, A, B, and C. 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.

The results of a Bonferroni analysis are summarized below.
                                                                 ___________


Interpret the Bonferroni analysis results.
◦ A has a significantly larger mean price than either of the other two supermarkets.
◦ C has a significantly larger mean price than either of the other two supermarkets.
◦ A has a significantly smaller mean price than either of the other two supermarkets.
◦ B and C have significantly different mean prices.
