Can anyone help me out with these questions?
11. A quality control manager at an aircraft cylinder manufacturing company knows that his company has been making cylinders with a 10% rate of defective units. He has instituted several measures designed to lower that defect rate. In a test of 20 randomly selected cylinders, only one is found to be defective. If the 10% defect rate hasn't changed, find the probability that among 20 units, one or none are defective. Based on the result, does it appear that the newly instituted measures are effective? 12. The Telektronic Company purchases large shipments of fluorescent bulbs and uses this reliability acceptance sampling plan: Randomly select and test 24 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% defect rate, what is the probability that this whole shipment will be accepted?
