A study at a community college shows that, of the 97 randomly selected first year students, 27 experienced stress. Of the 84 randomly selected second year students, 33 experienced stress. (Let pı be the proportion of first year students experienced stress and p2 the proportion of second year students experienced stress). Find a 88% confidence interval for the difference in proportions. Round answers to two decimal places. < pi P2 <
