You have purchased a state-of-the-art 3D printer and are planning to start a business selling printing services to fellow UTD students. You estimate the average print time of an order will be 7.7 hour with a standard deviation of 1.8 hours. During peak times each semester, i.e. end of course projects, you expect to receive an average of 2.6 orders per day. The inter-arrival times of orders have a coefficient of variation of 1. During these peak time, you plan to run the printer 24 hours a day and have friends help you so orders can be picked up as soon as they are completed. What is the expected duration, in hours, between when an order is received and when it is completed and ready to be picked-up? Report your answer to two decimal places.
