Moderate-90

According to a polling organization, 24% of adults in a large region consider themselves to be liberal. A survey asked 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 alpha = 0.10 level of significance. Click the icon to view the survey results. Because np_0 (1 - p_0) = ______ 10: the sample size is 5% of the population size, and the sample the requirements for testing the hypothesis satisfied. (Round to one decimal place as needed.)

Explanation / Answer

Total sample size is 58+52+90=200

thus n is 200

p is 0.24

thus n*p*(1-p)=200*0.24*0.76=36.48

thus greater than 10

Also sample mean is n*p=48
