(a) Set up ī and R control charts on this process. Is the process in control? Revise the control limits as necessary. (b) Estimate the mean and standard deviation of the process. (c) Is the layer thickness normally distributed? (d) If the specifications are at 450 ± 30, estimate the nrocess canahility
