Suppose there are 1150 students in your high school, and 28% of them take Spanish. You select a sample of 50 students in the school, and you want to calculate the probability that 15 or more of the students in your sample take Spanish. Which condition for the binomial setting has been violated here, and why does the binomial distribution do a good job of estimating this probability anyway?
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.
