A Local Consumer Reporter Wants to Compare the Average Costs

question 49

Essay

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 the Bonferroni analysis are summarized below. $$\begin{array} { l l l l } & & & \\\text { Supermarket } & \mathrm { A } & \mathrm { B } & \mathrm { C } \\\text { Mean Price } & 1 . 6 6& 1 . 8 0& 1.94\end{array}$$ Fully interpret the Bonferroni analysis.
