Exercise 2.46 asked the question: Are you more likely to smoke if your parents smoke? To shed light on the issue, a sample of 20- to 40-year old people was asked whether they smoked and whether their parents smoked. The results are stored the following way: Smoke: 1 = Do not smoke, 2 = Smoke and Parent: 1 = Neither parent smoked, 2 = Father smoked, 3 = Mother smoked, 4 = Both parents smoked. Test to determine whether there is enough evidence to infer that parents’ smoking and their children smoking are related.
