2. In 2010, shortly before a country's midterm elections, people in that country were dissatisfied with government and 54% of adults in the country thought that a third major party was needed. In a recent poll, 58% of 1001 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 2-test? Ho:p= Ha: P(1) - (Type integers or decimals.) What is the test statistic? (Round to two decimal places as needed.) za Identify the critical value(s). (2) (Round to two decimal places as needed.) What is the correct conclusion for the hypothesis test? A. Do not reject Ho; the data do not provide sufficient evidence to conclude that the percentage has changed from 54%. B. Reject Ho; the data do provide sufficient evidence to conclude that the percentage has changed from 54%. C. Do not reject Ho; the data do provide sufficient evidence to conclude that the percentage has changed from 54%. D. Reject Ho; the data do not provide sufficient evidence to conclude that the percentage has changed from 54%.
