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, 2483 of 3077 students surveyed said that freedom of the press was secure or very secure. In 2017, 1820 of 2006 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? O A Ho: P1 P2 OF HOP1 = Pa Ha: P1 = P2 H P1 > Pa Identify the test statistic. z= (Round to two decimal places as needed.) Identify the p-value. p-value = (Round to three decimal places as needed.) Since the p-value is the significance level of a = 0.01. the null hypothesis. There is evidence to support the claim that the 2016 proportion is the 2017 proportion b. Use the sample data to construct a 98% confidence interval for the difference in the proportions of college students in 2016 and 2017 who felt freedom of the press was secure or very secure. How does your confidence interval support your hypothesis test conclusion? The 98% confidence interval is (b. (Round to three decimal places as needed.) Because the confidence interval it appears that the two proportions are This conclusion the hypothesis test conclusion. Next
