A project was conducted with the objective of improving the wait time in a local hospital. The evaluation plan included waiting room time as one key waiting time process measure. Waiting room time was defined as the time elapsed between requesting that the patient be seated in the waiting room and the time he or she was called to be placed in an exam room. Initially, the target was set of 25 minutes. After implementing an improvement framework and process, the quality improvement team collected data on a sample of 355 patients. In this sample, the mean wait time was 23.05 minutes, with a standard deviation of 16.83 minutes. If you test the null hypothesis at the 0.01 level of significance, Is there evidence that the population mean wait time is less than 25 minutes?
