Assume the thickness X of washers to be normal with mean 2.75 mm and variance
Chapter 25, Problem 25.1.188(choose chapter or problem)
Assume the thickness X of washers to be normal with mean 2.75 mm and variance \(0.00024 \mathrm{~mm}^{2}\). Set up a control chart for \(\mu\). choosing \(\alpha=1 \%\), and graph the means of the five samples (2.74,2.76), (2.74 .2 .74), (2.79,2.81), (2.78,2.76),(2.71 .2 .75) on the chart.
