Suppose that a refrigeration process at Coldfoods, Ltd. Has a normally distributed output with a mean of 27.0 and a variance of 1.21. a. If the specifications are 27.0 3.25, compute C Cp and Cpm Is the process capable and centered? b. Suppose the mean shifts to 26.0 but the variance remains unchanged. Recompute and interpret these process capability indexes. c. If the variance can be reduced to 40 percent of its original value, how do the process capability in- dices change (using the original mean of 27.0)
