Pew research reported in 2013 that 15% of American adults do not use the internet or e-mail. They report a margin of error of 2.3 percentage points. The meaning of that margin of error is:
◦ They are pretty sure that the poll result differs from the actual percentage of American adults who don't use the internet or e-mail by 2.3% or less.
◦ They estimate that 2.3% of those surveyed answered incorrectly.
◦ If they repeatedly sampled from the population, and constructed a confidence interval for each estimate, about 2.3% of those intervals would capture the proportion of American adults who don't use the internet or e-mail.
◦ There is a 2.3% probability that their estimate is incorrect.
◦ They are 2.3% confident that their confidence interval captures the true proportion of American adults that don't use the internet or e-mail.
