Suppose a certain study reported that 27.7% of high school students smoke. Random samples are selected from high school that has 632 students. If a random sample of 60 students is selected, what is the probability that fewer than 19 of the students smoke?
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.
