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.

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?
