Suppose that about 77% of graduating students attend their graduation. A group of 31 students is randomly chosen, and let X be the number of students who attended their graduation. What is the distribution of X? X ~ Please show the following answers to 4 decimal places. What is the probability that at most 24 number of students who attended their graduation in this study? What is the probability that between 22 and 25 (including 22 and 25) number of students who attended their graduation in this study?
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.
