In a binomial experiment, we record four students' responses on whether they believe they would get a job within four months after graduation. We denote a positive response by "Y" and a negative response by "N". Noting that the table below does not necassarily list all of the possible outcomes, how many outcomes do possibly exist? Let X be a random variable representing the number of positive responses in the binomial experiement. Show the value of X for any outcome listed below. Outcome Value of X (Y, Y, Y, Y) (N, Y, Y, N) (N, N, N, N) (N, Y, N, Y) (Y, N, Y, N)
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.
