Bernoulli's Law
Statistical tables

The table 2 is used to draw conclusions for acceptance tests based on samples for which, either by exact representation (i.e., with delivery) or by valid numerical approximation (i.e., without delivery of a sample size n smaller than that of the batch, in practice $n<\frac{N}{10})$ ), we can consider that the probability of finding a defective part is distributed according to a Bernoulli distribution.

Example of use

To check the quality of a batch containing an unknown proportion p of defective parts, a sample of n = 50 parts is taken...
