Assume that the number of new visitors to a website in one hour is distributed as a Poisson random variable. The mean number of new visitors to the website is 1.8 per hour. Complete parts (a) through (d) below.
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.
Assume that the number of new visitors to a website in one hour is distributed as a Poisson random variable. The mean number of new visitors to the website is 1.8 per hour. Complete parts (a) through (d) below.
(A) What is the probability that in any given hour zero new visitors will arrive at the website?
(B) What is the probability that in any given hour zero new visitors will arrive at the website?
(C) What is the probability that in any given hour two or more new visitors will arrive at the website?
(D) What is the probability that in any given hour fewer than three new visitors will arrive at the website?
