She is now interested in the proportion of all couples who bought her book who stayed together. For a random sample of 225 couples who bought her book, she found that 173 of them stayed together. Based on this, compute a 99% confidence interval for the proportion of all couples who bought her book who stayed together. Then find the lower limit and upper limit of the 99% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. Lower Limit ____ Upper Limit____
