A survey¹ asked a random sample of n = 2752 US adults whether they had visited a public library in the last months. We see in that data that more females than males visit the library, but there is likely a confounding variable. The table below shows the survey results broken down by whether or not the participant is a parent of a minor. Find a 99 % confidence interval for pc - PN, the difference in proportion visiting the libary between those with children in the house and those without.
