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.
