My question is in regards to the statistical derivation of the sample size numbers in the Zero Acceptance Number Sampling Plan table by Nicholas Squeglia. I am unable to link to the sampling table my manufacturing company is using, but it can be seen if you copy and paste the following in your internet search bar: guidebook.dcma.mil/226/tools links file/stat-sample
Can someone please elaborate on how all the sample size numbers in the table are calculated? What statistics formula is used to calculate the sample sizes for a given lot size and AQL value?
For example for a lot size between 16 to 25 and AQL of 1%, the table says a sample size of 13 should be used. My question is what statistics equation/formula is used to calculate that 13 is the appropriate sample size for this given lot size and AQL? How is this calculation performed?
I understand how to use the table, however I want to understand where the numbers come from. If someone can please provide a detailed explanation I would truly appreciate it. Thank you.
