create an example to which the chi-square test of independence could be applied. Address the following: Identify two categorical variables for which a chi-square test of independence could be conducted. Describe the categories of each. Explain why these would be appropriate for this test. Predict whether or not the chi-square test result would be significant, and what this would imply about the variables.
