Twenty years ago, a very famous psychologist specializing in marriage counseling authored a book detailing the way in which she believed spouses should communicate. 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____

Introduction
In the given scenario, a highly well-known marriage counselor who wrote a book about how she thought couples should communicate twenty years ago is still frequently read today. The proportion of married couples who purchased her book is now something she is interested in. She discovered that 173 out of 225 randomly selected couples who purchased her book stayed together. We need to find the confidence at 99% level for the couples who stayed together after reading the book. We will find the lower and upper limits of the given condition in three decimals.
