Amanufacturer of cameras purchases large shipments of lenses from a supplier. you are the buying agent for the camera manufacturer. part of your job is to test each shipment of lenses to determine whether the shipment meets the quality standards promised by the supplier. the supplier has promised that less than 10% of its lenses are defective. you are perpetually skeptical of this claim, and so you take a random sample of 20 lenses in order to test the null hypothesis that at least 10% are defective, against the alternative hypothesis that fewer than 10% are defective.
