The manager for a regional taxi service wants to construct a control chart for determining whether the 10-drivers are under control with regard to the number of complaints filed. Accordingly, he sampled 100 rides from last year for each driver, with the following results:
Driver Number of Complaints
A 6
B 13
C 17
D 12
E 18
F 7
G 18
H 9
I 14
J 13
Analyze these data using a control chart that would provide for a 95% confidence interval, identifying the control limits and drivers, if any, that are outside the control limits.
