a) Calculate potential and actual capabilities and interpret these ratios. Which process is better?
b) If we shift the mean of Process B to the center, what is the fraction nonconforming for each process and revised actual capability of Process B. Which process should be selected? Why? (Assume that standard deviations stay the same)
