7. Consider the two processes (A and B). Each process's sample mean and sample standard deviation are shown in below table (the sample size n = 5 for each process). Process A Process B - 100 - 105 SA-3 5 Suppose that 20 of the parts manufactured by each process were assembled so that their dimensions were additive; that is, x x x, + + *20. The specifications on x are 2000 + 200. Decide whether you prefer to produce the parts using process A or process B by comparing Cpkm ratios. (HINT: Estimate a by 5/ca. )
