A newspaper poll found that 54% of the respondents in a random sample of voters in the city plan to vote for candidate Roberts. A 95 percent confidence interval for the population proportion is 0.54 ± 0.06. Based on this interval, what can the newspaper report? There is a 95% chance that Roberts will win. The race is too close to call, so no prediction about who will win should be made. With 95% confidence, there is convincing evidence that Roberts will win. The poll predicts Roberts will win, but there is a 5% chance that the prediction is incorrect due to sampling error.
