The Party of Nonvoters From past elections, nonvoters are those who are either not registered to vote or are considered unlikely to vote in an upcoming election. Nonvoters are very different demographically from likely voters. Nonvoters are more racially and ethnically diverse. 43% of those who are not likely to cast a ballot are Hispanic, African or other racial and ethnic minorities, roughly double the percentage amoung likely voters(22%) (Source: Pew Research Center, October, 2014, "The Party of Nonvoters"). Suppose you interview 10 people who are considered nonvoters. Round answers to 4 decimal places. a.) What is the probability that 5 of them are an ethnic minority? b.) What is the probability that more than 8 are an ethnic minority? c.) What is the probability that at least 8 are not an ethnic minority? d.) What is the probability that fewer than 5 are not an ethnic minority?
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.
