Problem 1. Consider a fast food restaurant where customers arrive and get in line according to a Poisson process with an average rate of 120 customers per hour. The restaurant has one line and the amount of time it takes the cashier to serve a customer is exponentially distributed with a mean of 2 minutes. Let X_t denote the number of customers in line at time t. 1. Give the state space of the chain (X_t)t≥0. 2. For each state...

The day after Thanksgiving is known as "Black Friday" as
retailers open early on Friday morning, or sometimes late at night
on Thanksgiving Day itself, to start the holiday shopping season.
However, there is a current social movement afoot to allow
employees to enjoy the Thanksgiving holiday by discouraging
consumers from patronizing stores that open on Thanksgiving Day
evening. SaMart believes that consumers will not follow the social
pressure and will continue to show up in large numbers at midnight...

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...

At a certain coffee shop, all the customers buy a cup of coffee and some also buy a doughnut. The shop owner believes that the number of cups he sells each day is normally distributed with a mean of 330 cups and a standard deviation of 21 cups. He also believes that the number of doughnuts he sells each day is independent of the coffee sales and is normally distributed with a mean of 130 doughnuts and a standard deviation...

8. A sporting goods store announces a "Wheel of Savings" sale. Customers select the merchandise they want to purchase, then at the cash register they spin a wheel to determine the size of the discount they will receive. The wheel is divided into 12 regions, like a clock. Six of those regions are red, and award a 10% discount. The three white regions award a 20% discount and two blue regions a 40% discount. The remaining region is gold, and...

2. The number of customers entering Heal's in a given hour is Poisson distributed with mean 30. The amount of money (in pounds) spent by each customer is uniformly distributed over (0, 500). Let T denote the total amount of money spent by customers in Heal's in one hour. Find ET). You should define any notation you use and note any assumptions you make. HINT 1: Write T as a sum of random variables, noting that the number of random...
