Case 1, Ariel said: "To clarify a little bit more if for n=126, Ac=5 and N=2000, the true lot fraction defective is 2.36% at 0.03 of incoming defective."

I don't understand what the 0.03 is?

For n=126, Ac=5, Alpha=0.05, Beta=0.05: AQL=0.020937, RQL=0.081622. If p'=.0236 then Pa=0.9211

Case 2, Ariel said: "If now N=50000 to keep p' at 2.36% n should change to =160 an Ac to =6. Is this correct?"

For n=160, Ac=6, Alpha=0.05, Beta=0.05: AQL=0.020709, RQL=0.072669. If p'=.0236 then Pa=0.9138

For both cases, the lot size did not enter the calculation.
