Hanging Toilet Paper: Suppose that you plan to take a random sample of hanging toilet paper rolls in your town, with the goal of estimating the proportions of rolls that are hung so that the paper comes out over the top, as opposed to coming out underneath. You want to determine how many rolls to sample for a 95% confidence interval to have a margin of error no larger than ±.06. The population standard deviation of rolls that are hung so the paper comes out over the top is .43. Determine the necessary sample size.
