Question:

For the double sampling plan N=2000, n1 =80, c1 = 1, r1 = 3, n2 = 100, c2 = 2, r2 = 3, construct and interpret the ASN curve. Suppose that process average nonconforming rate is 1.5%. Would you prefer the stated double sampling plan or a single sampling plan with n = 100, c = 2 in order to minimize ASN?
