An automotive manufacturer design of their bearings has diameter specifications listed as 7 0.03 cm. a) What is the Upper Specification (tolerance) limit for the bearing? What is the Lower Specification (tolerance) Limit for the bearing? b) The manufacturer's process produces parts with an average diameter of 7.02 cm and a standar deviation of 0.02 cm. What is the sigma capability of the process? c) Is the process capable of meeting the specifications? The target sigma capability is 3. d) If you reduce the standard deviation of the process, will it lead to increase in the sigma capability
