My company is using the following sampling table based on Nicholas Sequigla's Zero Acceptance Number Sampling Plan:

My question is where do the sampling size numbers in the table come
from? What statistics equation/formula is used to arrive at these
sampling size numbers? How is this statistics formula used to get these
numbers? I have read that the numbers may come from Hypergeometric distribution, Poisson distribution, or Binomial distribution. I have tried applying these formulas but still do not understand how they got the numbers in the table.

For example, the table states that for a lot size of 51 to 90 and AQL
of 1%, the sample size is 13. My question is how was it determined
that 13 is the sufficient sample size? There must be a statistics
formula used to calculate this 13.

If someone can proivde me with a thorough explanation, I would truly appreciate it.
