Suppose that a cold storage facility to store perishable foods has a temperature normally distributed output with a mean of 25.0F and a variance of 1.44F. a. If the specifications are 25.0F 3.25F, compute C C and C. Is the process capable and centered? b. Suppose the mean shifts to 23.0F but the variance remains unchanged. Recompute Cr C and C interpret these process capability indices. C. If the variance can be reduced to 40 percent of its original value, how do the process capability indices change (using the original mean of 25.0F)?
