3. a. A process is in statistical control with x

3. a. A process is in statistical control with x = 39.7 and R = 2.5. The control chart uses a sample size of n = 2. Specifications are at 40 5. The quality characteristic is normally distributed. Estimate the potential capability of the process. Estimate the actual process capability. How much improvement could be made in process performance if the mean could be centered at the nominal value? b. C. a 4. A process is in control with x = 75 and 5 = 2. The process specifications are at 80 + 8. The sample size is n = 5. Estimate the potential capability. b. Estimate the actual capability. How much could process fallout be reduced by shifting the mean to the nominal dimension? Assume that the quality characteristic is normally distributed. c
