A simple random sample of size n = 15 is drawn from a population that is normally distributed. The sample mean is found to be x? = 63 and the sample standard deviation is found to be s = 16. Construct a 90% confidence interval about the population mean. The lower bound is The upper bound is (Round to two decimal places as needed.)
