A large department store found that it averages 362 customers per hour. Assume that the standard deviation is 29.6 and a random sample of 40 hours was used to determine the average. Find the 98% confidence interval of the population mean.
Customers arrivals at a checkout counter in a department store per hour have a Poisson distribution...
Customers arrivals at a checkout counter in a department store per hour have a Poisson distribution with parameter λ = 7. Calculate the probabilities for the following events. (a) (2 points) Exactly seven customers arrive in a random 1-hour period. (b) (4 points) No more than two customers arrive in a random 1-hour period. (c) (4 points) At least three customers arrive in a random 1-hour period.
Customers arrive at a store randomly, following a Poisson distribution at an average rate of 20 per hour. What is the probability of exactly 3 arrivals in a 12 minute period?
Customers arrive at a store randomly, following a Poisson distribution at an average rate of 20 per hour. What is the probability of exactly 3 arrivals in a 12 minute period?

Customers enter a store according to a Poisson process of rate λ = 5 per hour. Independently, each customer buys something with probability p = 0.8 and leaves without making a purchase with probability q = 1 − p = 0.2. Each customer buying something will spend an amount of money uniformly distributed between $1 and $101 (independently of the purchases of the other customers). What are the mean and the standard deviation of the total amount of money spent...

Customers arrive at a grocery store at an average of 1.9 per minute. Assume that the number of arrivals in a minute follows the Poisson distribution. Provide answers to the following to 3 decimal places. Part a) What is the probability that exactly two customers arrive in a minute? Part b) Find the probability that more than three customers arrive in a two-minute period. Part c) What is the probability that at least seven customers arrive in three minutes, given...

(1 point) You are interested in finding out the mean number of customers entering a 24-hour convenience store every 10-minutes. You suspect this can be modeled by the Poisson distribution with a a mean of = 3.59 customers. You are to randomly pick n = 57 10-minute time frames, and observe the number of customers who enter the convenience store in each. After which, you are to average the 57 counts you have. That is, compute the value of X...
Customers enter the camera department of a store at an average rate of five per hour....
Customers enter the camera department of a store at an average rate of five per hour. The department is staffed by one employee, who takes an average of 8.0 minutes to serve each arrival. Assume this is a simple Poisson arrival, exponentially distributed service time situation. (Use the Excel spreadsheet Queue Models.) a-1. As a casual observer, how many people would you expect to see in the camera department (excluding the clerk)? (Round your answer to 2 decimal places.) a-2....
