Does owning an indoor dog really help bring down borderline high systolic blood pressure? To answer this question, a random sample of twelve subjects with chronically borderline high sys- tolic blood pressure was obtained. Their systolic blood pressure was recorded. They then received a house-trained dog to live indoor with them. After one month, their blood pressure was taken again. At the 2.5% significance level, can you conclude that owning a pet will reduce the average systolic blood pressure?

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.
