medical test is conducted to determine whether someone has a disease. Suppose that 8% of population has this disease. The test has a 95% chance of detecting the disease, if the person has the disease, and a 90% chance of indicating that the disease is absent, if the person does not have the disease. What is the probability that a person has the disease, given that this person has tested positive(5mks).
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.
