6.5 Q: A hospital emergency department is monitoring the time required to admit a patient using Xbar
and R charts. Table 6E.1 presents summary data for 20 subgroups of two patients each (time is in
minutes).
a) Use these data to determine the control limi
6.55 Q: Xbar and R charts with n = 4 are used to monitor a normally distributed quality characteristic.
The control charts parameters are:
UCL (x) = 815, CL (x) = 800, LCL (x) = 785
UCL (R) = 46.98, CL (R) = 20.59, LCL (R) = 0
Both charts exhibit control.
6.1 Q: A manufacturer of components for automobile transmissions wants to use control charts to
monitor a process producing a shaft. The resulting data from 20 samples of 4 shaft diameters that have

A: For manufacturers and service providers, there are 8-11 dimensions of quality to be
considered, each one weighing differently with different consumers.
