Statistics

Refer to given Exercise. If we want to control the number of imperfections per 100 m2, how would this affect the control chart? What would the control limits be? In terms of decision making, would there be a difference between this problem and given Exercise, depending on which chart is constructed? What conclusions can you draw from this?

Exercise
The number of imperfections in bond paper produced by a paper mill is observed over a period of several days. Table shows the area inspected and the number of imperfections for 25 samples. Construct a control chart for the number of imperfections per square meter. Revise the limits, if necessary, assuming special causes for the out-of-control points.
