For each of the following processes, a sample of size 400 is collected in order to estimate the process mean and variability. Process Mean Sample Standard Deviation (s or σ ^) Lower Spec Upper Spec A 29.3 0.74 26.8 31.8 B 119.6 2.56 115.5 132.5 Indicate which measure of process capability (C_p vs.C_pk) appears the more appropriate to use for each process, and state why. Compute the appropriate measure of process capability for each process.
