Assuming that 30% of randomly selected adults have high cholesterol (with a level at least 240 mg/dL or are taking medicine to reduce cholesterol), If we randomly select 5 adults at random, answer the following: a) What is the probability that exactly 2 of the 5 adults have high cholesterol? Additionally, what is the probability that AT LEAST 1 of the 5 adults have high cholesterol? What is the probability that between 2 and 4,inclusive, of the 5 adults have high cholesterol? Additionally, find the mean and standard deviation for the number of adults in groups of 5 who have high cholesterol.
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.
