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 in minutes) for a sample of patients at offices that do not have a wait-tracking system and wait times for a sample of patients at offices with a wait-tracking system without wait with Wait Tracking System Tracking System 23 31 62 10 15 13 21 17 32 11 45 35 10 10 26 2 16 11 35 10
