Suppose a store averages 9 customers per hour, and we want to find the probability the store will have at least 25 customers over a 3-hour period. If we use the Poisson calculator on StatCrunch, what value must we supply for the mean? Question is complete. Tap on the red indicators to see incorrect answers. 20

Shoppers arrive at a retail store at an average of 10 per minute (Poisson) where the service rate is almost 207 per hour (Poisson). What is the average number of shoppers in the system with 3 cashiers? (10 pts) What is the minimum number of cashiers needed to keep the average time in the system under three minutes? (10 pts)

(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...

3. While taking a daily one-hour walk, a person finds coins on the ground according to a Poisson process at a rate of 30 coins per hour, 60% of the coins are pennies, 20% are nickels and 20% are dimes. a. Determine Poisson process rate for each type of coin. b. What is an expression for the value of the coins found during an hour (Use P for number of pennies, N for number of nickels and D for number...

1) The number of calls received at a certain information desk has a Poisson Distribution with an average of 6 calls per hour. (15 points) (a) Find the probability that there is at exactly one call during a 15 minute period. (You cannot use tables here - show all work) (b) Find the probability that at least 6 calls are received during a 30 minute period. (you may use tables here) ******************************** 2) Note that for the above problem, the...

5 Boutique Store Consider a boutique store in a busy shopping mall. Every hour, a large number of people visit the mall, and each independently enters the boutique store with some small probability. The store owner decides to model X, the number of customers that enter her store during a particular hour, as a Poisson random variable with mean 2. Suppose that whenever a customer enters the boutique store, they leave the shop without...

We are interested in determining the probability that a retail store will meet its daily revenue goal of $100. Analysis of sales history indicates that daily demand, D is random and independent of the demand on other days. Assume D follows the distribution below P(D=d) = 0.3, d=0 0.3, d=1 0.2, d=2 0.1, d=3 0.1, d=4 Furthermore, due to a complicated discount structure, the shop has determined that their revenue per day can be modeled as R(s) = −100 cos(20s)...

Use Poisson Distribution to solve problems 6-7 6. The number of calls received by a car towing service averages 1.25 per hour Use the Poisson distribution to find the probability that in a randomly selected hour the number o calls is 2. Show the result of probability calculations and circle one of the multiple choice answers. (6 points) A) 0.1865 B) 0.2238 C) 0.1586 D) 0.3524

Suppose the number of emails sent from a system follows the Poisson distribution, which averages 30 times per hour. a. Find the probability that an email will not be sent for a certain minute. b. Let T be a random variable that represents the time between when an email is sent and the next email is sent., Find the probability distribution of T and use this to determine the probability of more than 10 minutes of time between when an...
