Cornell University researchers conducted a survey of a random sample of New York firefighters, some of whom had participated in the 9/11 rescue efforts. The report's title is "On the Front Line: The Work of First Responders in a Post-9/11 World" To see the report, click here . We use data from this report to investigate the question: Are alcohol- related problems among New York firefighters associated with participation in the 9/1 1 rescue? 1. A test of independence may be appropriate if we are examining the relationship between two categorical variables in one population. For this situation what is the population? What are the variables? 2. What are the hypotheses for our test of independence? 3. Here are the data from the report.
