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. Because npo (1- Po) = 34.3 > 10; the sample size is less than 5% of the population size, and the sample is given to be random, the requirements for testing the hypothesis are satisfied. (Round to one decimal place as needed.) Identify the null and alternative hypotheses for this test. Let p represent the population proportion of adults in this region who consider themselves to be liberal. Họ: p = 0.22 versus H,: p 0.22 (Type integers or decimals. Do not round.) Find the test statistic, zo, for this hypothesis test. Zo = (Round to two decimal places as needed.)
