Tell whether the conclusion is sensitive to the level of significance chosen, identify cells that contribute
the most to the chi-square test statistic, and check for small expected frequencies. If necessary, you can
calculate the p-value by using Excel’s function =CHIDIST(test statistic,deg_freedom). Note: Exercises marked
