16) The university police department must write, on average, five tickets per day to keep department revenues at budgeted levels. Suppose the number of tickets written per day follows a Poisson distribution with a mean of 4.5 tickets per day. Interpret the value of the mean. A) If we sampled all days, the arithmetic average number of tickets written would be 4.5 tickets per day. B) The number of tickets that is written most often is 4.5 tickets per day. C) Half of the days have less than 4.5 tickets written and half of the days have more than 4.5 tickets written. DI The mean has no interpretation since 05 tickket can never be written

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.
