The billing department of a local department store sends monthly statements to the store’s customers. For those statements to reach the customer in a timely fashion, the addresses on the envelopes must be correct. Occasionally errors are made with the addresses. The billing department estimates that errors are made 2 percent of the time. For this continuous process, in which an error in the address is considered a nonconforming unit, what is the probability that in a sample size of eight, one address or less will be incorrect?
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.
