How Much Do You Read? ~ A nation-wide survey conducted in 2019 asked a random sample of US adults, "During the past 12 months, about how many books did you read either all or part of the way through? Please include any print, electronic, or audiobooks you may have read or listened to." The survey results reported the mean number of books read to be 14.7. Kelly is a library science major and wonders if adults who have a library card report reading more books in a year than the nationally reported mean. She obtains a random sample of 19 adults with a library card from her community library and asks them the same survey question. From her results she calculates a sample mean of 16.7 and a standard deviation of 4.2201.
