Chapter 19, Problem 17SE

a.

To determine

Find the control limits for the $\overline{x}$ chart for the samples of sizes 10, 20, and 30.

b.

To determine

Explain about the control limits when the sample size increases.

c.

To determine

Explain the process if Type I error is made.

d.

To determine

Explain the process if Type II error is made.

e.

To determine

Find the probability of Type I error for samples of sizes 10, 20, and 30.

f.

To determine

Explain the advantage of increasing the sample size for control chart purposes.

Find which error probability is reduced as the sample size is increased.
