Dr. Mendoza developed a test to measure boredom tolerance. The test results for the group of 20,000 adults are shown in the following table. Determine if the table satisfies a probability distribution (you must justify your answer). If yes, find the mean, variance, and standard deviation. X P(X) 0 0.686 1 0.195 2 0.077 3 0.022 4 0.013 5 0.007
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.
