a) If the average number of nonconforming units is 2.5, what is the probability that a sample will contain 3 or less nonconforming units? Use the Poisson distribution. b) A steady stream of income tax returns has a proportion nonconforming of 0.05. What is the probability of obtaining 3 nonconforming units from a sample of 30? Use the binomial distribution.
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.
