Consider the accompanying 2 × 3table displaying the sample proportions that fell in the various combinations of categories (e.g., 13% of those in the sample were in the first category of both factors).

a. Suppose the sample consisted of n = 100 people. Use the chi-squared test for independence with significance level .10.

b. Repeat part (a), assuming that the sample size was n = 100 0.

c. What is the smallest sample size n for which these observed proportions would result in rejection of the independence hypothesis?
