Refer to given Exercise. What is the average sample number of incoming lots that are 2% nonconforming? What is the average total inspection for this quality level of 2% nonconforming?
Exercise
Consider a double sampling plan given by the following parameters: N =1200, n1= 50, c1= 1, r1=4, n2= 110, c2= 5, r2=6. Find the probability of accepting lots that are 4% nonconforming. What is the probability of rejecting a lot on the first sample?
