3.43. A production process operates with a constant 0.05% nonconforming output. Every 2 hours a random sample of 100 units is taken from this process and evaluated. If more than two nonconforming units are found in this sample, the process is stopped and quality engineering personnel search for the cause of excessive nonconforming production. What is the probability that a sample contains 2 or more nonconforming units? What do you think of this procedure? If this process operates with a constant 0.05% nonconforming rate of output for 8 hours each day, what is the probability that the process will be stopped over the next 2 weeks ( 10 days) when the percent nonconforming has not changed
