Boardwork Electronics manufactures 250,000 circuit boards per month. A
random sample of 4,000 boards is inspected every week for five character-
istics. During a recent week, three defects were found for one characteristic,
and two defects each were found for the other four characteristics. If these
inspections produced defect counts that were representative of the
lation, what are the dpmo's for the individual characteristics and what is the
overall dpmo for the boards?
