You are responsible for the quality control of a certain par

You are responsible for the quality control of a certain part bought from a supplier. Inspection tests destroy the part, so you must use sampling. A 5% or less defective rate is tolerable, but in your sample of 100 from a lot of 10,000, you discover 8 parts are defective. Should you accept or reject the shipment if you are willing to erroneously reject a good shipment 10% of the time?
