In 2010, shortly before a country's midterm elections, people in that country were dissatisfied with government and 61% of adults in the country thought that a third major party was needed. In a recent poll, 64% of 1042 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. Click here to view page 1 of the table of areas under the standard normal curve. Click here to view page 2 of the table of areas under the standard normal curve. What are the hypotheses for the one-proportion z-test? Ho: p=0.61; H₂: P0.61 (Type integers or decimals.) What is the test statistic? z = (Round to two decimal places as needed.) Identify the critical value(s). (Round to two decimal places as needed.) What is the correct conclusion for the hypothesis test? OA. Reject Ho: the data do provide sufficient evidence to conclude that the percentage has changed from 61%. OB. Do not reject Ho; the data do not provide sufficient evidence to conclude that the percentage has changed from 61%. OC. Reject Ho; the data do not provide sufficient evidence to conclude that the percentage has changed from 61%. O D. Do not reject Ho: the data do provide sufficient evidence to conclude that the percentage has changed from 61%.
