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.

(c) Give a careful and complete statement of the central limit theorem.
Given a probability distribution of x values where n =
sample size, u
= the mean of the x distribution, and o = the standard deviation of the x distribution. Even if the x distribution is
not normal, if the sample sizen is sufficiently large (n
30 in most cases), the central limit theorem tells us that the x distribution is approximately
the mean of the x
distribution is H
and the standard deviation of the x distribution is o, =
