Question 5: A poll conducted in 2013 found that 52% of US-based adult Twitter users get at least some news from Twitter. The standard error for this estimate was 2.4%. Assuming that the necessary conditions hold, construct a 99% confidence interval, and interpret what this interval says in the context this scenario. Also, answer whether the following two statements are true or false and justify your reasoning. 1. Since the standard error is 2.4%, we can conclude that 97.6% of all US-based adult Twitter users were included in the poll. 2. To reduce the standard error of the estimate, we should collect less data (i.e. poll fewer people)
