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.

Finding a Job
Elena and Clare are each working on a project about how high school students are having trouble finding jobs. Tney each find the proportion of students
without jobs from a random sample, thern use a computer to do 1,000 simulations using the proportion they found and report the rasults.
Elena says, "The proportion of high school students without jobs is about O.70 with a margin of error of 0.280.
Clare says, "The proportion of high school students without jobs is about 0.74 with a margin of error of 0.138."
Both students reported the margin of error based on 2
standard deviations from their simulations. What are the
mean and standard doviation each student found? For at
least one student, show your reasoning.
