Cоpper wires аre cоаted with а thin plastic cоating. Samples of four wires are taken every hour, and the thickness of the coating (in mils) is measured. The data from the last 30 samples are presented in the table. The means are = 150.075, and = 6.97. Calculate the 3σ control limit for the R chart. Is the variance under control? If not delete the samples that are out of control and recompute and . Compute the 3σ control limits for the chart. Based on the 3σ limits, is the process mean in control? If not, at what point is it first detected to be out of control?
