we have an ongoing production process that has historically operated with 1% non conforming output. Every hour, a sample of 15 units is collected and inspected for non-conforming units . If one or more non-conforming units are found, the process is stopped and inspected for problems. a) What percentage of the time will the process need to be stopped? b) if the process suddenly deteriorates to 4% non-conforming output, What is the probability that it will be stopped on the very next sample? c) What percentage of non-conforming units would make a line stoppage 90% probable?
