Samples change

Samples change will affect alpha (manufacturer) risk, and beta (Customer) risk. O curve sampling change affects customer risk more dramatically than S curve sampling change. When detecting same spoilage rate, sampling more means less customer risk, but more manufacturer risk. S curve change is samples remains unchanged with more spoilages found. And O curve change is that samples increase with spoilages reamain unchanged.
