What is the probability that when a lot is received a second sample will be needed for inspection before sentencing? Assume that the quality of incoming lots is p=0.05 and the plan parameters are: n1=n239, c1=1,c2%3D3.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
