A simple random sample of size n = 19 is drawn from

A simple random sample of size n = 19 is drawn from a population that is normally distributed. The sample mean is found to be x 64 and the sample standard deviation is found to be s=20. Construct a 90% confidence interval about the population mean. The lower bound is 56.06 The upper bound is 71.94 (Round to two decimal places as needed.)
