Question:
The specifications require that the height of shock shafts have \(\mu=1.6\) meters and \(\sigma=0.03\) meters.
(a) Use the specifications to calculate a central line and three-sigma control limits for an \(\bar{x}\) chart with \(n=5\).
(b) Use the specifications to calculate a central line and three-sigma control limits for an \(R\) chart with \(n=5\).
(c) Plot the following means and ranges, obtained in 20 successive random samples of size 5 , on charts based on the control-chart constants obtained in part (a) and (b), and discuss the process.
