Suppose that 160 out of a random sample of 200 letters mailed in the United States were delivered the day after they were mailed. Based on this, compute a 99% confidence interval for the proportion of all letters mailed in the United States that were delivered the day after they were mailed. 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. (If necessary, consult a list of formulas.) Lower limit: Upper limit: X
