On atypical Saturday morning, cars arrive at a mean rate of eight per hour, with arrivals tendingto follow a Poisson distribution. Find the following:a. The average number of cars in lineb. The average time cars spend in line and service
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.
