Of the 3055 people who responded to survey, 1669 stated that they currently use social media. a) Use the data from this survey to construct a 97% confidence interval estimate of the proportion of adults who use social media. Record the result below in the form of (#,#). Round your final answer to four decimal places. b) Can you conclude that the percentage of adults who use social media has changed? Explain.
