Question

In​ 2010, shortly before a​ country's midterm​ elections, people in that country were dissatisfied with government and 59​% of adults in the country thought that a third major party was needed. In a recent​ poll, 62​% of 1182 adults in the country felt the same way. At the 20​% significance​ level, do the data provide sufficient evidence to conclude that the percentage of all adults in the country who now think that a third major party is needed has changed from that in​ 2010? Use the​ one-proportion z-test to perform the appropriate hypothesis test.
