The hypergeometric distribution is appropriate when sampling without replacement from a finite population. In the context of acceptance sampling, the population corresponds to the total number of units in the lot, and the sample is the subset of units that are inspected. Thus, when the lot size is small, it is more appropriate to use the hypergeometric distribution to calculate the OC curve. The Poisson and binomial distributions are more appropriate for larger lot sizes, where the number of nonconforming units is expected to be smaller and the sampling is close to a continuous process. The p-chart, on the other hand, is used to monitor the proportion of nonconforming units in a process, rather than for acceptance sampling.
