A hospital would like to determine the mean length of stay for its patients having major surgery. A sample of 18 patients showed a sample mean of 4.5 days and a sample standard deviation of 3.8 days. Assume that the length of stay is approximately normally distributed. Find the upper limit of a 99 % confidence interval for the mean length of stay for patients having surgery at the hospital. Round your answer to two decimal places.
