From a large number of actuarial exam scores, a random sample of 325 scores is selected, and It is found that 224 of these 325 are passing scores. Based on this sample, find a 90% confidence Interval for the proportion of all scores that are passing. Then flnd 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.
