Example 3.21 from Statistics, 3.4 Contingency Tables
a. Complete the table.
Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.
a. There are 45 females in the sample; 18 prefer the coastline and 16 prefer hiking near lakes and streams. So, we know there are 45 − 18 − 16 = 11 female students who prefer hiking on mountain peaks.
Continue reasoning in this way to complete the table.
| Sex | The Coastline | Near Lakes and Streams | On Mountain Peaks | Total |
|---|---|---|---|---|
| Female | 18 | 16 | 11 | 45 |
| Male | 16 | 25 | 14 | 55 |
| Total | 34 | 41 | 25 | 100 |
How did it go?
