Suppose the prevalence of alcoholism among college students is 20% among those living in group housing and 5% among those living in other situations such as an apartment or at a parent's house. Suppose also that 25% of college students live in group housing. a. What is the probability that a randomly selected college student has alcoholism and lives in group housing? b. What is the overall prevalence of alcoholism among college students? c. Among those college students with alcoholism, what proportion lives in group housing?
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.
