Question:
Repeat Exercise 8, using the \(S\) chart in place of the \(R\) chart.
Data From Exercise 8:
Samples of eight bolts are taken periodically, and their diameters (in \(\mathrm{mm}\) ) are measured. The following table presents the means, ranges, and standard deviations for 25 consecutive samples.
The means are \(\overline{\bar{X}}=9.9892, \bar{R}=0.2628\), and \(\bar{s}=\) 0.0880 .
