= 1 =2 3 4 From a large number of actuarial exam scores, a random sample of 200 scores is selected, and it is found that 138 of these 200 are passing scores. Based on this sample, find a 90% confidence interval for the proportion of all scores that are passing. 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: X ? Upper limit
