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.

Question

To determine the effectiveness of a diet in reducing the amount
of cholesterol in the bloodstream, 100 people are put on a diet. After they
have been on the diet a sufficient amount of time, their cholesterol count will
be taken. The utritionist running this experiment has decided to endorse
the diet if at least 65 people have a lower cholesterol count after going on the
diet. What is the probability that the nutritionist endorses the new diet if,
in fact, it has no effect on the cholesterol level? (If the diet has no effect on
the cholesterol level, then a person's cholesterol level is equally likely to go
up or down.)
