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.

Suppose that you randomly selected 26 adults. Assume 18% of the population smoke. Round all answers to 2
decimal places.
a) Using the Range Rule of Thumb, what is the minimum number of usual smokers we can expect to get out of
26 adults?
b) Using the Range Rule of Thumb, what is the maximum number of usual smokers we can expect to get out of
26 adults?
c) Would it be unusual to randomly select 26 adults and get 10 smokers?
No, since 10 is between the maximum and minimum usual values.
Yes, since 10 is not between the maximum and minimum usual values.
