Question
A poll conducted in 2013 found that 52% of U.S. adult Twitter users get at least some news on Twitter. The
standard error for this estimate was 2.4%, and a normal distribution may be used to model the sample
proportion. Construct a 99% confidence interval for the fraction of U.S. adult Twitter users who get some news
on Twitter, and interpret the confidence interval in context.
