In 2016, the Pew Research Center reported the results of a survey about public library usage. A nationally representativ sample of 1601 people aged 16 and older who were living in the United States completed the survey.

Give your answer as an interval in the form (lower limit, upper limit). Use decimal notation. Give the limits to two decimal places.) 99% confidence interval:
