The number of telephone calls that arrive at a call center is often modeled as a Poisson random variable. Assume that on the average there are 10 calls per hour. What is the probability that there are more than 40 calls in three hours? a) 0.0414 b) 0.0323 0.0145 0.0574
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.
