What is the reasoning behind setting the upper and lower control limits ± 30- from the mean? OA. We know that 99.73% of natural variation is contained within 30, and thus any data point outside of the limits is likely due to assignable variation OB. The limits of the Z table are set at ± 30% OC. 95.45% of the time, the sample averages will fall within 30- if the process has only natural variation OD. We know that 99.73% of assignable variation is contained within ± 30-, and thus any data point outside of the limits is likely due to natural variation +
