In a program designed to help patients stop smoking, 221 patients were given sustained care, and 83.3% of them were no longer smoking after one month. Use a 0.01 significance level to test the claim that 80% of patients stop smoking when given sustained care. The test statistic for this hypothesis test is: Find the P-value:
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.
