Results from a Chembio test for hepatitis C among HIV-infected patients (based on data from a variety of sources) showed 337 subjects with positive test results including 2 false positive results. There were 1,163 negative results, including 10 false negative results. What is the probability that a randomly selected subject has a positive test result given he has no hepatitis C ?
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.
