A process is in control with x = 75 and s = 2. The process specifications are at 80 + 8. The sample size n = 5. (a) Estimate the potential capability. (b) Estimate the actual capability. (c) How much could process fallout be reduced by shifting the mean to the nominal dimension? Assume that the quality characteristic is nor- mally distributed.A process is in control with x = 100, s = 1.05, and n = 5. The process specifications are at 95 + 10. The quality characteristic has a normal distribution. (a) Estimate the potential capability. (b) Estimate the actual capability. (c) How much could the fallout in the process be reduced if the process were corrected to operate at the nominal specification?A process is in statistical control with x = 199 and R = 3.5. The control chart uses a sample size of n =4. Specifications are at 200 1 8. The quality char- acteristic is normally distributed. (a) Estimate the potential capability of the process. (b) Estimate the actual process capability. (c) How much improvement could be made in process performance if the mean could be cen- tered at the nominal value
