According to a polling organization, 22% of adults in a large region consider themselves to be liberal. A survey asked 200 respondents to disclose their political
philosophy: Conservative, Liberal, Moderate. Treat the results of the survey as a random sample of adults in this region. Do the survey results suggest the proportion is
higher than that reported by the polling organization? Use an a = 0.05 level of significance.
E Click the icon to view the survey results.
Find the test statistic, zo, for this hypothesis test.
Zo = 2.73 (Round to two decimal places as needed.)
Determine the P-value for this hypothesis test.
P-value = 0.003 (Round to three decimal places as needed.)
State the conclusion.
O A. Reject Hn. There is sufficient evidence at the a = 0.05 level of significance to conclude that the proportion is higher than that reported by the polling
organization.
O B. Reject Hn. There is not sufficient evidence at the a= 0.05 level of significance to conclude that the proportion is higher than that reported by the polling
organization.
O C. Do not reject Ho. There is not sufficient evidence at the a = 0.05 level of significance to conclude that the proportion is higher than that reported by the
polling organization.
O D. Do not reject Ho. There is sufficient evidence at the a = 0.05 level of significance to conclude that the proportion is higher than that reported by the polling
organization.
