The number of bills for each day of the week is shown in Table D.6. Does this provide evidence that some days of the week are more popular (have more bills) than others?

Table D.6

In Data 2.12 on page 119, we introduce the dataset RestaurantTips containing information on the tipping patterns of patrons of the First Crush bistro in northern New York state. The data from 157 bills include the amount of the bill, size of the tip, percentage tip, number of customers in the group, whether or not a credit card was used, day of the week, and a coded identity of the server. The first four variables are quantitative and the last three are categorical.

Data 2.12 on page 119

The owner of a bistro called First Crush in Potsdam, New York, is interested in studying the tipping patterns of its patrons. He collected restaurant bills over a two-week period that he believes provide a good sample of his customers. The data from 157 bills are stored in RestaurantTips and include the amount of the bill, size of the tip, percentage tip, number of customers in the group, whether or not a credit card was used, day of the week, and a coded identity of the server.
