The probability of flu symptoms for a person not receiving any treatment is 0.017. In a clinical trial of a common drug used to lower​ cholesterol, 18 of 935 people treated experienced flu symptoms. Assuming the drug has no effect on the likelihood of flu​ symptoms, estimate the probability that at least 18 people experience flu symptoms. What do these results suggest about flu symptoms as an adverse reaction to the​ drug? ​(a) ​P(X≥18​)=nothing ​(

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.
