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.

An SRS of n=80 finds 16 smokers. We want to test whether the national smoking prevalence (i.e., the population proportion) is significantly difference than 0.25 at 95% confidence level. Assume that we can use a z-test.
What is your conclusion?
answer choices
Since p-value is greater than ?, we can say the national smoking prevalence is truly different from 0.25
Since p-value is greater than ?, there is not significant evidence to say that the national smoking prevalence is truly different from 0.25
Since p-value is less than ?, there is not significant evidence to say the population proportion of smokers in Community Y is truly different than the national average
Since p-value is less than ?, we can say that the national smoking prevalence is truly different from 0.25
