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?

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.

What are the hypotheses for the one-proportion z-test?
Ho: p=D; H,: p
(Type integers or decimals.)
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. Reject H,; the data do not provide sufficient evidence to conclude that the percentage has changed from 57%.
OC. Do not reject Hn; the data do not provide sufficient evidence to conclude that the percentage has changed from 57%.
