In a survey of 1065 people, 797 people said they voted in a recent presidential election. Voting records show that 72% of eligible voters actually did vote. Given that 72% of eligible voters actually did vote, find probability that among 1065 randomly selected voters at least 797 actually did vote then determine what results suggest
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.
