A recent poll indicated that 30% of Americans were satisfied with how things were going in the USA. For the question below, assume a sample of 20 Americans is selected as part of a study to gauge the state of the nation. What is the probability that all 20 people are happy with how things are going? Question: Is the correct formula to test this in excel =BINOM.DIST(20,20,.30,FALSE)? > I want to confirm this is a Binomial distribution and that we are not using the cumulative option.
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.
