Suppose the number of admissions to the emergency room at a small hospital follows a Poisson distribution, but the incidence rate changed on different days of the week. On a weekday, there are on average two admissions per day, while on a weekend, there are on average three admissions per day. What is the probability of at least two admissions for an entire week?
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.
