 A project manager at Q Corporation has a commitment to deliver 200

cylinders to a customer. The internal diameter of these cylinders must be 60 centimetres. The tolerance is +1 and -0.5 centimetre. If the mean value of the production process is 60.4 and the standard deviation is 0.5,a-      Calculate the process capability index (CP and CPk) and indicate if the process is capable.b-     How many cylinders the PM should plan to produce in order for 200 of them to meet specification.c-     What should be the standard deviation in order for the process to become capable?
