For a process, we measure one important characteristic of its products and find that its process mean is 38.325 cm and the standard deviation is 0.225 cm. The specification limits are 38.1 ± 0.9 cm. By using the Process Capability Index measure, what is the current quality level (in sigmas) of the process? 2.5 sigmas 3 sigmas 3.5 sigmas 4.5 sigmas For the same process and specification in the above question, what is the quality level (in sigmas) the process can achieve if the process means can be adjusted to be centered at the nominal value, i.e., 38.1 cm? 4 sigmas 4.5 sigmas 5 sigmas 3.5 sigmas
