Question

Quizplus · Accepted Answer

The centerline for a control chart for defects is calculated as (Total number of defects observed / Total number of units observed). In this case, the total number of defects observed over the 20 samples is 200 and each sample contains one completed tax return. Therefore, the total number of units observed is also 20.

So, the centerline would be (200/20) = 10. Hence, the correct choice is B.
