Example 22.1 A company is engaged in the manufacture of battery cells in its plant. The process is said to be under control if the mean life of battery cells is 1,200 hrs with a standard deviation of 75 hrs. Considering these values to be the process average and process dispersion, you are required to deter- mine the 3-sigma control limits for x-chart for samples of size 16.
