A local newspaper conducts a phone survey to judge public opinion about a referendum. The referendum passes if a majority of voters vote yes. Of the 950 respondents to the survey, 450 say they plan to vote yes. Is this sufficient information for the newspaper to predict the outcome of the referendum vote, or should they say it is "too close to call"? Conduct your test twice, once using the binomial distribution directly and again using the normal approximation to the binomial distribution. How do the results compare?
