Only 0.1 % of individuals in a certain population have a particular disease ( an incidence rate of 0.001) of those who have the disease ,95% test positive when a certain diagnostic test is applied of those who do not have the disease,90% test negative when the test is applied. Suppose that an individual from this population is randomly selected and given the test.what is the probability that his/ her diagnostic test is negative
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.
