Problem 3: Understanding the chi-squared test of independence of categorical random variables The problem has two sub-problems that should help understand the chi-squared test of independence. a) For the chi-squared test of independence between two categorical variables, we use the fact that the MLE for the probability that a multinomial trial is of category i is ni /n, where ni is the number of trials that fall into category i, and n is the total number of trials. Prove the...

The purpose of this activity is to gain experience conducting a chi-square test of independence using technology. Recall the report On the Front Line: The Work of First Responders in a Post-9/11 World. We will use data from this report to investigate the question: Are alcohol-related problems among New York firefighters associated with participation in the 9/11 rescue? Here again are our observed data: No Risk for Alcohol Problems Moderate to Severe Risk for alcohol problems Participated in 911 rescue...

Suppose that you wish to perform a chi-square test of independence. The two variables under consideration are sex and blood type. True or false, if the two variables are not associated, we would expect that in the sample, the number of women with a given blood type would be roughly equal to the number of men with the same blood type? If the statement is false, rewrite it so that it is true.
