Suppose the prevalence (p=.32) of type II diabetes follows a binomial distribution in a community. Researchers want to sample 15 households from the community for a new study investigating ethnographic ties to the chronic illness. What is the cumulative probability of selecting 8 or more diabetics in the sample from the community? What is the probability of selecting between 6 and 10 diabetics in the sample from the community?
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.
