The task times are shown in the table below: Task Time (in minutes per unit) 1 4 2 5 3 3 4 3 Question 8 3 pts (c) As before, assume that the process is empty at noon, and from noon to 3 pm one unit enters the process in every 5 minutes. On average, how long does the flow unit arriving between noon to 3 pm will wait to be served? Express your answer in minutes, round to two decimals if needed
