A manufacturer of aircraft engines uses a sequential sampling plan to accept or reject incoming lots of microprocessors used in the engines. Assume an AQL of 1 percent and an LTPD of 5 percent. Determine a sequential sampling plan assuming α =.05, β = .10. Graph the acceptance and rejection regions. Consider the sequential sampling plan described in the above problem. Suppose that a lot of 1,000 microprocessors is inspected. Suppose that the 31st, 89th, 121st, and 122nd chips tested are found defective. Assuming the sequential sampling plan derived in the above Problem, will the lot be accepted, rejected, or neither by the time the 122nd chip has been tested?
