Question

So, the brewery selected it’s place and now needs to hire folks. After some testing, they expect to have approximately 2,000 customers per week. Since they will be open 7 days a week, they need to hire people to help serve their beer. They know that Friday and Saturday will drive sales. Between these 2 days, they will get 50% of their weekly sales. So, Friday has 25% of sales and Saturday has 25% of the sales. As for Sunday to Thursday, they assume they will get 10% of sales on each of those days.

Q1) How many people do they expect to get each day?

Sunday	Monday	Tuesday	Wednesday	Thursday	Friday	Saturday
200	200	200	200	200	500	500

Q2) Each day of the week, they have set hours. Based upon those hours and the number of customers per day, determine the average number of customers per hour.

Day	Open	Close	Avg Cust/hr
Sunday	12:00pm	10:00pm	20
Monday	4:00pm	10:00pm	33.33
Tuesday	4:00pm	10:00pm	33.33
Wednesday	4:00pm	10:00pm	33.33
Thursday	4:00pm	10:00pm	33.33
Friday	4:00pm	12:00am	62.50
Saturday	12:00pm	12:00am	41.667

Q3) Using the “Multiple” file from the author, use the average customers per hour data above and a server can handle 12 customers per hour, add servers such that the wait time for a customer to order their drink is under: 5mins, 3mins, 1min (NOTE: There is a change in time units.)

Day	5 min	3 min	1 min
Sunday	3	N/A	N/A
Monday	9	N/A	N/A
Tuesday	9	N/A	N/A
Wednesday	9	N/A	N/A
Thursday	9	N/A	N/A
Friday	13	N/A	N/A
Saturday	10	N/A	N/A

****I NEED HELP WITH QUESTION 4****
Q4) We know that the values you just calculated are based upon the average number of people entering the brewery. Use a simulation and an appropriate probability distribution (cough cough Poisson Cough cough) to determine the 80^th and 90^th percentile for people entering each day.
