Public Policy Polling (PPP), a reputable polling company, asked the following question in a previous Halloween-eccentric public opinion poll:“If zombies took over the world and human civilization collapsed, how long do you think you could survive: less than one week, less than one month, less than six months, less than one year, or more than a year?” Of the 1,200 likely voters who were asked this question, 324 said “Less than one week”.

According to 2021 Gallup poll, 37% of adult Americans consider themselves to be “moderate”. Cincinnati State students taking MAT 131 were asked to disclose their political philosophy and the results are located in the variable IDEOLOGY. For a certain semester, 73 students reported themselves to be “moderate” out of 182 students who were asked the question. Treat the results of the survey as a random sample of all Cincinnati State students who will take MAT 131. Do the results suggest the proportion of Cincinnati State students taking MAT 131 who consider themselves to be “moderate” is different than that reported by Gallup? Use an alpha level of 0.01.Are the results of the test statistically significant?
