A variables sampling plan (VSP) for defectives is required for a process with two-sided spec limits USL/LSL = 75±5. The VSP must meet the following conditions ■ Accept 95% of 0.5% defective lots (Hint: What are the AQL and alpha values?) ■Reject 90% of 2% defective lots (Hint: What are the RQL and beta values?) a. Design the VSP assuming that the population standard deviation is known. (Assume σ = 1) b. Design the VSP assuming that the population standard deviation is unknown. c. Should you accept or reject a lot in the σ unknown case if the sample delivers x = 72.0 and s = 1.5? (You don't have the sample data to use the MINITAB menu. You will have to do the calculation by hand.)

Question
Transcribed Image Text:A variables sampling plan (VSP) for defectives is required for a process with two-sided spec limits
USL/LSL = 75±5. The VSP must meet the following conditions
■ Accept 95% of 0.5% defective lots (Hint: What are the AQL and alpha values?)
■Reject 90% of 2% defective lots (Hint: What are the RQL and beta values?)
a. Design the VSP assuming that the population standard deviation is known. (Assume σ = 1)
b. Design the VSP assuming that the population standard deviation is unknown.
c. Should you accept or reject a lot in the σ unknown case if the sample delivers x = 72.0 and
s = 1.5? (You don't have the sample data to use the MINITAB menu. You will have to do the
calculation by hand.)
