Suppose a pharmaceutical company develops a drug that helps children stop wetting the bed at night. They claim it has a success rate of 80%. You doubt this, thinking they have exaggerated the success rate. So you test this by giving the drug to a sample of 10 bed-wetting children, and only 5 of the 10 stop wetting the bed. What is the probability, under their claim, that five or fewer will stop bed-wetting?
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.
