According the World Bank, only 8% of the population of Uganda had access to electricity as of 2009. Suppose we randomly sample 20 people in Uganda. Let X = the number of people who have access to electricity. The distribution is a binomial. What is the distribution of X? X ~ ? B U N (,) 2. What is the probability that between 3 and 6 (including 3 and 6) people have access to electricity in this study?
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.
