In a recent year, about 22% of Americans 14 years and older are single. What is the probability that in a random sample of 150 Americans 14 or older, more than 21 are single? Round the final answer to at least 4 decimal places and intermediate z-value calculations to 2 decimal places. P(X > 21)=
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.
