A quality-control sensor should flag about half of items as "Pass" (P) and half as "Fail" (F) when fed a test stream designed to be random. For 24 items, the outcomes are: P P P P P P P P P P P P F F F F F F F F F F F F. Under random behavior you would expect mixing throughout, not all P's followed by all F's. Is the pattern consistent with random behavior?
