The information in Table below is the number of daily emergency service calls made by the volunteer ambulance service for the last 50 days. Number of calls Frequency 0 8 1 10 2 22 3 9 4 1 Convert this information on the number of calls to a probability distribution. Is this an example of a discrete or continuous probability distribution? What is the mean number of emergency calls per day?
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.
