Families in Poverty. In 2012, 32.7% of all families in a particular country had incomes below the poverty level. During that same year, of 400 randomly selected M-city families, 110 had incomes below the poverty level. At the 5% significance level, do the data provide sufficient evidence to conclude that, in 2012, the percentage of families with incomes below the poverty level was lower among those living in M-city than among all the other families in that country?
