Chad runs a DMV that prides itself on short lines. Chad knows that on a given day, the DMV will have an average of 30 customers per hour, and each customer takes one hour with an employee. What is the probability that exactly 12 customers enter the DMV in one half hour? (Use Poisson Equation)
Homework Answers
Here, λ = 15 and x = 12
As per Poisson's distribution formula P(X = x) = λ^x *
e^(-λ)/x!
We need to calculate P(X = 12)
P(x = 12) = 15^12 * e^(-15) /12!
= 0.0829

During lunchtime at a certain fast food restaurant, customers arrive at an average rate of 7 customers every 5 minutes. assume a poisson distribution to find the probability that: A) exactly 12 customers arrive in a given 10 minute interval (perform this calculation using an appropriate formula, showing the setup.) b) between 5 and 10 customers (inclusive) arrive in a given 5 minute interval (show how you can answer this from the table) c) after a customer arrives, find the...

The average number of customers arriving at a drive-through window of a bank branch is 39 per hour during lunch hours. Use X to denote the number of arrivals in a 5 minute time interval. Assume the customers arrive independently and the number of arrivals within each 5 minutes follows a Poisson distribution. Keep at least 4 decimal digits if the result has more decimal digits.

Question 1: Frantic Francine runs one of the most popular restaurants in Manhattan. Francine knows on average how many customers to expect on a given day, but some days just end up busier and some days slower. To prepare for the lunch rush, Francine schedules enough cooks (L) to meet the expected number of customers. Francine’s production function is given by q = K 0.5 L 0.5, where K represents kitchen equipment. Cooks and kitchen equipment are imperfect substitutes (Francine...

QUESTION 1 Customers arrive at a hair salon according to a Poisson process with an average of 16 customers per hour. Which of the following is most likely true, based on this information: a. The hair salon serves customers on a walk-in basis (rather than by appointment times) b. If 10 customers arrive in the first hour, it is likely that 22 customers will arrive in the next hour. c. If the salon can serve an average of 20 customers...

The first three answers are correct. Need the final two.
Problem 10-16 Customers enter the camera department of a store at the average rate of nine per hour. The department is staffed by one employee, who takes an average of 3.0 minutes to serve each arrival. Assume this is a simple Poisson arrival, exponentially distributed service time situation. Use Exhibit 10.9. a-1. As a casual observer, how many people would you expect to see in the camera department (excluding the...
