We are examining two processes for machining a part. Process A produces parts which have a mean length of $100$ and a standard deviation of $3.$ Process B produces parts which have a mean length of $105$ and standard deviation $1.$ The design specifications for the part are $100+10.$ Calculate: $1.$ Cp for each process $2.$ Cpk for each process $3.$ The percentage of parts which are out of specification limits for each
