Public opinion about marriage has changed over the last few years. In 1965, 21% of people polled answered yes when asked "Do you think that marriage as an institution is becoming obsolete?" A recent sample of 216 college students yielded 68 'yes' answers to the same question. Use a 0.015 significance level to test the claim that a greater proportion of people answer 'yes' now than in 1965.
