Exercise 1 Page 693

A two-way table is a frequency table that displays data collected from one source that belongs to two different categories. One category of data is represented by rows and the other is represented by columns. We want to organize the given information in a two-way table. To do so, we will follow three steps.

1. Construct an empty table with the appropriate column and row headers.
2. Fill in the table with the given values.
3. Find the rest of values.

Let's do these three things one at a time.

Constructing the Table

We are told that customers were asked whether they liked chicken or beef and wether they liked rice or pasta. This information is enough to determine the appropriate column and row headers for our table.
