Question: The Telektronic Company purchases large shipments of fluorescent bulbs and uses this acceptance-sampling plan: Randomly select and test 20 bulbs, then accept the whole batch if there is only one or none that doesn’t work. If a particular shipment of thousands of bulbs actually has a 4.5% rate of defects, what is the probability that this whole shipment will be accepted? [Assume a binomial probability distribution.]
