13. College Education The pie chart shows the results of a survey in which U.S. parents were asked their opinions on whether a college education is worth the expense. An economist claims that the distribution of the opinions of U.S. teenagers is different from the distribution given for U.S. parents. To test this claim, you randomly select 200 U.S. teenagers and ask each whether a college education is worth the expense. The table shows the results. At α = 0.05, test the economist’s claim.
