In testing of electric cables, the probability that any particular cable will be defective is .04. Let X be the number of defective cables found in a batch of 300 cables. Use normal approximation to the binomial distribution to find the probability that X is at most 20.
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.
