Margin of Error (as a percentage): Confidence Interval: to Find the margin of error and confidence interval for the percentage of U.S. adults who regularly use Facebook as a news source, at the 99% level of confidence. Report answers to at least 2 decimal places. Margin of Error (as a percentage): Confidence Interval: The more error we allow, the less precise our estimate. Therefore, as the confidence level increases, the precision of our estimate O increases decreases O stays roughly the same
