A compact disc (CD) player manufacturer has decided to use an SQC chart system to monitor quality in the operations management system. A QC inspector who tests the finished product inspects the CD players. The test involves playing a CD. If the unit plays the CD, it passes the inspection; if the unit fails to play the CD, the unit fails the inspection. Six samples of four hundreds units each were taken and resulted in 9, 12, 5, 7, 4,...
