A process mean is centered between the specification limits and PCR = 1.33. Assume that the process mean increases by 1.5Ïƒ.

(a) Calculate PCR and PCR_k for the shifted process.

(b) Calculate the estimated fallout from the shifted process and compare your result to those in Table 15-4. Assume a normal distribution for the measurement.
