A poll asked college students in 2016 and again in 2017 whether they believed the First Amendment
guarantee of freedom of the press was secure or threatened in the country today. In 2016, 2087 of 3103
students surveyed said that freedom of the press was secure or very secure. In 2017, 1930 of 2988
students surveyed felt this way.
a. Determine whether the proportion of college students who believe that freedom of religion is secure or
very secure in this country has changed from 2016. Use a significance level of 0.05.
b. Use the sample data to construct a 95% confidence interval for the difference in the proportions of
college students in 2016 and 2017 who felt freedom of religion was secure or very secure. How does
your confidence interval support your hypothesis test conclusion?
