Question

1. 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?

2. For the double sampling plan N= 2200, n₁= 60, c₁=1, r₁=5, n₂= 120, c₂= 4, r₂=5, construct the ASN curve. Within what range of proportion nonconforming values would you prefer the stated double sampling plan over a single sampling plan with n= 85, c= 2 in order to minimize ASN?
