What is the difference between control limits and specification limits?

Suppose that the specification limits for a production process are LSL = 0.02 and USL =...

Suppose that the specification limits for a production process are LSL = 0.02 and USL = 0.10, with the nominal specification being 0.06. a)_____________ What is the sigma level if the process standard deviation is 0.01. b)_____________ If the process is centered, what is the DPMO?

A process has a Cpk = 1.35 and is centered between the specification limits. (a) What is the DPM of the process? (b) If the mean of the process increases by 1.5σ the DPM would be?

A process is in control and normally distributed with ? control chart limits of 45 and...

A process is in control and normally distributed with ? control chart limits of 45 and 15. The subgroup size is 4. Suppose the process variance suddenly triples while process mean remains unchanged. What is the probability that the first subsequent subgroup average will fall outside the control limits? What are the ? probability and ARL? Suppose the process variance suddenly triples while process mean shifts downward to 10. What are the β probability and ARL now?

Suppose that a control chart is used to monitor ? ̅ where the control limits are set to 3?? ̅ and the warning limits are set to 2?? ̅. Answer the following: (a) If the false alarm cost per occurrence is $1000. What is the expected false alarm cost every 100 samples. (b) If the warning inspection cost is $100. What is the expected warning inspection cost every 100 samples. (c) Suppose the current sample size of 10 is quadrupled,...

The upper and lower control limits on control charts are usually set at a distance of...

The upper and lower control limits on control charts are usually set at a distance of +/- three times the standard deviation from the center line of the control chart. Use independent research to find the reasons why. Make sure you use the concept of type I and type II error in your discussion. Under what circumstances might a manager consider the use of limits at two times the standard deviation. What should the manager keep in mind when setting...

Which of the following statements about the upper and lower control limits of a control chart...

Which of the following statements about the upper and lower control limits of a control chart is true? Group of answer choices The upper and lower control limits for a p chart depend on the sample size. The lower control limit of a p chart will ALWAYS be a negative value. The upper control limit of an X-bar chart does NOT depend on the average range R-bar. The upper and lower control limits of an R chart are always the...
