A poll conducted in 2013 found that 52% of U.S. adult Twitter users get at least some news on Twitter (Pew, 2013). 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. (please round all percentages to 2 decimal places) The 99% confidence interval is %, %) Interpret the meaning of your confidence interval: There is a 99% probability that the proportion of U.S. adult twitter users who get some news on Twitter is within our confidence interval O 99% of confidence intervals will be contain the correct sample proportion of U.S. adult twitter users who get some news on Twitter O We are 99% confident that the true proportion of U.S. adult twitter users who get some news on Twitter is within our confidence interval
