Pew Research Center conducted a poll in 2016 and determined that 28% of Americans preferred to use an ereader over printed books. Curious about this statistic, I polled 100 of my staff. The results were very similar to the 2016 poll. Of the 100 staff polled, 40 of them said they prefer ereaders over printed books.
Using a .05 confidence level, do the results suggest my staff are in line with the typical American reader?
