Ashipment of 60,000 capacitors arrives at a manufacturing plant. the quality control engineer at the plant obtains a random sample of 600 capacitors and will reject the entire shipment if 11 or more of the capacitors are defective. suppose that 4.5% of the capacitors in the whole shipment are defective (but the engineer doesn’t know this actual percentage). what is the probability the engineer accepts the shipment? should a shipment with 4.5% defective capacitors be accepted? do you think the engineer’s acceptance policy is sound?
