#25 A simple random sample of size n equals 40 is drawn from a population. The sample mean is found to be x overbar equals 121.3 and the sample standard deviation is found to be s equals 12.2. Construct a 99% confidence interval for the population mean. The lower bound is nothing. (Round to two decimal places as needed.) The upper bound is nothing. (Round to two decimal places as needed.)
