determine whether the random variable X has a binomial distribution. If it does state the number of trials n. If it does not, explain why not. Twenty students are randomly chosen from a math class of 70 students. Let X be the total number of student absences. Part 1 The random variable -does -does not have a binomial distribution Part 2 Choose the statement that explains why X does not have a binomial distribution, more than one may apply -The Number of trials is not fixed -There are more than two possible outcomes for each trial -The probability of success is not the same for each trial -The trials are not independent -X does not represent the number of successes that occur
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.
