od truck serves lunch every weekday. Suppose each academic year has 160 weekdays, and the number of customers per day follows a Poisson distribution with a parameter 80. (a) What do you say about the distribution of the average number of cus-tomers (averaged over 160 weekdays)? (b) What is the probability that the total number of customers in an academic year exceeds 8400?
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.
