ANSWER ALL THREE PLEASE

2. What types of operations exhibit the greatest natural variation in their output? How useful is statistical process control to these operations?

4. Suppose the range within a sample was calculated and then plotted on an R-chart, but this sample range fell outside the lower control limit on the R-chart. Does this necessarily represent defective production?

5. Why would a consumer tolerate a certain amount of defectiveness in a product? When is this more common?

If the Central Limit Theorem were to suddenly become invalid, how would the current use of control charts then be misguided? 4.
