Single Sampling Plan for Attributes

 

A single sampling plan for attributes has been agreed on as an acceptance sampling plan:  N=1,000,000, n=250 c=4

Create the appropriate graphics for the plan.  In your discussion of the graphics, and the inherent risks of sampling plans please consider the following:

1.     If the producers risk is set at 0.5%, what would the resulting AQL?

2.     If the RQL is set at 4%, what would be the resulting consumers risk?

3.     If a screen and scrap plan is put into place, determine the maximum average outgoing quality level (AOQL)

4.     Determine the average total inspection at the peak AOQL

5.     Which distribution was used to determine these values?
