In 2010, shortly before a country's midterm elections, people in that country were dissatisfied with government and 57% of adults in the country thought that a third major party was needed. In a recent poll, 61% of 1059 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?

What is the test statistic? z= (Round to two decimal places as needed.) Identify the critical value(s). V (Round to two decimal places as needed.) What is the correct conclusion for the hypothesis test? O A. Do not reject Hn; the data do provide sufficient evidence to conclude that the percentage has changed from 57%. O B.
