A hospital would like to determine the mean length of stay for its patients having abdominal surgery. A sample of 16 patients revealed a sample mean of 6.8 days and a sample standard deviation of 1.6 days. Assume that the lengths of stay are approximately normally distributed. Find a 95% confidence interval for the mean length of stay for patients with abdominal surgery. Round the endpoints to two decimal places, if necessary
