3. The time until a certain pain medication reach es maximum level in the bloodstream has been measured in 22 patients. The sample aver age time was 27 minutes and the sample standard deviation was 4 minutes. Assume that the time to reach the maximum level is norm ally dis- tributed. (a) Compute a 90% confidence interval for the mean time until the maximum level of medication is reached. Compute a 95% confidence interval for the mean time until the maximum level (b) of medication is reached. Compute a 99% confidence interval for the mean time until the maximum level (c) of medication is reached.
