Do Teen Problems Differ Based on Income Level? A survey aksed US teens whether they consider anxiety/depression a major problem among their peers. The table below shows the results of whether teens said it was a major problem or not, based on household income level of the teens. Income Less than $75,000 More than $75,000 Total Major problem 386 258 644 Not major problem 150 126 276 Total 536 384 920 We are interested in estimating the difference in proportion who think it is a major problem, between the two groups.
