laboratory blood test is 95% effective in detecting a certain disease when it is in fact, present. However, the test also yields a false positive result for 1% of the healthy persons tested. That is, if a healthy person is tested, then, with probability 0.01, the test result will imply that he or she has the disease. If 0.5% of the population actually has the disease, calculate the probability that a randomly selected person will get a positive test result
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.
