The tensile strengths of wires in a certain lot of size 400 are specified to exceed 5

Question:

The tensile strengths of wires in a certain lot of size 400 are specified to exceed 5 kilograms. Consider an acceptance sampling plan based on a sample of n = 10 wires and acceptance number α = 1.

a. Find the producer’s risk if the AQL is 2.5%.

b. Find the consumer’s risk if the lot fraction failing to meet specifications is p₁ = .15.

c. Draw a rough sketch of the operating characteristic curve for the sampling plan. Do you think the sampling plan is acceptable? Explain.
