Assignment Help Operation Management
Reference no: EM132041495

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.
