What is the mean or expected number of customers that will arrive in a five-minute period? Round your answer to the nearest whole number. λ = per five minute period Assume that the Poisson probability distribution can be used to describe the arrival process. Use the arrival rate in part (a) and compute the probabilities that exactly 0, 1, 2, and 3 customers will arrive during a five-minute period. Round your answers to four decimal places. x P(x) 0 1 2 3 Delays are expected if more than three customers arrive during any five-minute period. What is the probability that delays will occur? Round your answer to four decimal places. P(Delay Problems) =
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.
Willow Brook National Bank operates a drive-up teller window that allows customers to complete bank transactions without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 36 customers per hour or 0.6 customers per minute.
