A pharmaceutical company makes tranquilizers. We wish to find the 89% confidence interval. It is assumed that the distribution for the length of time they last is approximately normal. The standard deviation for all lengths of time for the tranquilizer is 0.21 hours. Researchers in a hospital used the drug on a random sample of 33 patients. The effective period of the tranquilizer for each patient (in hours) is shown in the table below. Round all answers to the nearest hundredth.
