Chapter 10, Problem 4SE

Red Cars and Stop Signs The table shows the raw data for the results of a student survey of $22$ cars and whether they stopped completely at a stop sign or not. In the Color column, “Red” means the car was red, and “No” means the car was not red. In the Stop column, “Stop” means the car stopped, and “No” means the car did not stop fully.

Create a two-way table to summarize these data. Use Red and No for the columns (across the top) and Stop and No for the rows. (We gave you an orientation of the table so that your answers would be easy to compare.)

Are the two variables categorical or numerical?
