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 (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.
