Quizplus · Accepted Answer

A p chart is a statistical process control chart used to monitor the proportion of nonconforming items in a sample. It helps to determine whether a process is stable and in control or not. In this case, the owner of the newspaper wants to see if the percentage of papers delivered on time is erratic, which means they are checking for control. Therefore, the best choice is B, in control. The other options (A, C, and D) do not characterize the p chart correctly in this context.
