Question: Suppose that a cookie making process has a normally distributed out put with a mean of 80 grams and variance of 16 grams. (a) If

Suppose that a cookie making process has a normally distributed out put with a mean of 80 grams and variance of 16 grams.

(a) If the specifications are 80.0 12 grams, compute Cp, Cpu, Cpl, and Cpk., and interpret these process capability indexes.

(b) Is the process capable and centered? Explain.

(d) If the variance can be reduced to 56.25 percent of its original value, how do the process capability indices change (using the original mean of 80 grams?
