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, 2488 of 3085 students surveyed said that freedom of the press was secure or very secure. In 2017, 1796 of 2038 students surveyed felt this way. Complete parts (a) and (b). a. Determine whether the proportion of college students who believe that freedom of the press is secure or very secure in this country has changed from 2016. Use a significance level of 0.01. Consider the first sample to be the 2016 survey, the second sample to be the 2017 survey, and the number of successes to be the number of people who believe that freedom of the press is secure or very secure. What are the null and alternative hypotheses for the hypothesis test? A. $H_0: p_1 = p_2$ $H_a: p_1 \ne p_2$ D. $H_0: p_1 = p_2$ $H_a: p_1 < p_2$ B. $H_0: p_1 = p_2$ $H_a: p_1 \ne p_2$ E. $H_0: p_1 = p_2$ $H_a: p_1 > p_2$ C. $H_0: p_1 < p_2$ $H_a: p_1 = p_2$ F. $H_0: p_1 > p_2$ $H_a: p_1 = p_2$
