In a study to estimate the proportion of wives who regularly watch soap operas, it is found that 52 of 200 wives in Denver. 31 of 150 wives in Phoenix and 37 of 150 wives in Rochester watch at least one soap opera. Use a 0.05 level of significance to test the hypothesis that there is no difference among the true proportions of wives who watch soap operas in these 3 cities.
