2. Analyze the data using the appropriate analysis. What can you say about the varia- tion among the cities in this study? Among fines for the three types of violations? Can Tukey's procedure be of use in further delineating any significant differences you may find? Would confidence interval estimates be useful in your analysis?

Do you risk a parking ticket by parking where you shouldn't or forgetting how much time you have left on the parking meter? Do the fines associated with various parking infractions vary depending on the city in which you receive a parking ticket? To look at this issue, the fines imposed for overtime parking, parking in a no parking zone, and parking next to a fire route were recorded for 11 cities in the province of Ontario.10
