Question
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 system and
wait times for a sample of patients at offices with a wait-tracking system.

(a) Considering only offices without a wait-tracking system, what is the z-score for the 10th
patient in the sample (wait time = 37 minutes)?
If required, round your intermediate calculations and final answer to two decimal places.
Z-score =
0.206
(b) Considering only offices with a wait-tracking system, what is the z-score for the 6th patient in
the sample (wait time = 37 minutes)?
If required, round your intermediate calculations and final answer to two decimal places.
Z-Score =
1.82
How does this z-score compare with the z-score you calculated for part (a)?
The input in the box below will not be graded, but may be reviewed and considered by your
instructor.

(c) Based on z-scores, do the data for offices without a wait-tracking system contain any
outliers?
No
Based on z-scores, do the data for offices with a wait-tracking system contain any outliers?
No
