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 200 couples who bought her book, she found that 154 of them stayed together. Based on this, compute a 90% 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 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. (If necessary, consult a list of formulas.) Lower limit: || Upper limit:|
