Chapter 10, Problem 5SE

a.

To determine

Eliminate the necessary samples that helps to bring the process in control.

b.

To determine

Obtain the estimate of ${\sigma }_{\overline{X}}$ using the $\overline{R}$.

c.

To determine

Step up a CUSUM control chart for the target mean $\mu$, and the estimate of ${\sigma }_{\overline{X}}$.

d.

To determine

Check whether or not the process mean is in control, otherwise detect the sample at which the process is out of control.

e.

To determine

Check whether or not the process mean is in control, otherwise detect the sample at which the process is out of control based on Western Electric rules.
