17.34 Does income relate to use of the Internet?

The study mentioned in the previous exercise also asked about income. Among Internet users, 493 reported income of less than $50,000, and 378 reported income of $50,000 or more. (Not everyone answered the income question.) The corresponding numbers for nonusers were 477 and 200. Repeat the analysis using an indicator variable for income of $50,000 or more as the explanatory variable. What do you conclude?
