The percentage of high school graduates applying to multiple colleges has been increasing over the past several years. According to an association in a certain region, 34% of high school students applied to nine or more colleges in 2015. A random sample of 368 high school graduates in 2018 was selected and 133 of them applied to nine or more colleges. Complete parts a through c. a. Construct a 95% confidence interval to estimate the actual proportion of high school graduates that applied to nine or more colleges in 2018. The confidence interval has a lower limit of and an upper limit of [ (Round to three decimal places as needed.) b. What is the margin of error for this sample? The margin of error is (Round to three decimal places as needed.) c. Is there evidence that this proportion has changed since 2015 based on this sample? This sample evidence that this proportion has changed since 2015, since the
