Suppose that the average waiting time for a patient at a physician's office is just over 29 minutes. In order to address the issue of long patient wait times, some physicians' offices are using wait-tracking systems to notify patients of expected wait times. Patients can adjust their arrival times based on this information and spend less time in waiting rooms. The following data show wait times (minutes) for a sample of patients at offices that do not have a wait-tracking...

One of the most important patient care performance indicators for stroke care is the “Door-to-Needle (DTN)” time (i.e., the number of minutes elapsed between patient’s arrival at the emergency department of a hospital and the infusion of a necessary medication. The stroke program manager of a hospital wants to determine...
