m 1. As contracting officer for a company that manufactures lifters, you must decide whether to accept a shipment of machine parts from a supplier for use in the construction of lifters. Each shipment contains 100 new parts and you sample 10 and inspect them for defects. Your supervisor instructs you to accept a shipment only if you find no more than 1 defective part. 1. What is the probability that you will accept a shipment which has 10% defective parts? 2. On the average, how many defectives would you expect in a sample of size 10 if
