Chapter 15, Problem 2E(choose chapter or problem)
Twenty-five samples of size 5 are drawn from a process at one-hour intervals, and the following data are obtained:
\(\sum_{i=1}^{25} \bar{x}_{i}=362.75\)
\(\sum_{i=1}^{25} r_{i}=8.60\)
\(\sum_{i=1}^{25} s_{i}=3.64\)
(a) Calculate trial control limits for \(\bar{X}\) and R charts.
(b) Repeat part (a) for \(\bar{X}\) and S charts.
