Suppose that the average waiting time for a patient at a physician's office is just over minutes Suppose that the average waiting time for a patient at a physician's office is just over minutes. To
address the issue of long patients', wait times, some physicians' offices are using waittracking 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 waittracking system and wait times for a sample
of patients at offices with such systems. The data are stored in HI Group Assignment T
data file sheet
a Calculate the mean and median patient wait times for offices;
i with a waittracking system?
ii without a waittracking system?
b Calculate the variance and standard deviation of patient wait times for offices;
i with a waittracking system?
ii without a waittracking system?
c Create a box plot for patient wait times for offices;
i with a waittracking system and review the information from the box plot?
ii without a waittracking system and review the information from the box plot?
d Do offices with a waittracking system have shorter patient wait times than offices without a
waittracking system? Explain.
