PART B. A concerned citizen wants to determine if the chlorine content of their water is still safe to drink. By health standards, the mean allowable chlorine content should be at most 1 mg/L. The health of the people will be at risk if the chlorine content exceeds the said value. To verify this, he randomly selected 50 water samples from different houses and analyzed their chemical content. kon made by amalieat hom wwwfaticon.com 1.

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.
