A simple random sample of size n=21 is drawn from a population that is normally distributed. The sample mean is found to be x= 68 and the sample standard deviation is found to be s = 18. Construct a 90% confidence interval about the population mean. The lower bound is The upper bound is (Round to two decimal places as needed.)
