Tommy claims that he blindly guessed on a 20-question true/false test, but then he got 16 of the questions correct. Using the binomial calculator, you find out that the probability of getting 16 or more correct out of 20 when π = .5 is 0.0059. This probability of 0.0059 is the probability that... he would get 80% correct if he took the test again. he would get this score or better if he were just guessing. he was guessing blindly on the test.
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.
