Five administrative assistants use an office copier. The average time between arrivals for each assistant is 40 minutes, which is equivalent to an arrival rate of 1/40 = 0.025 arrivals per minute. The mean time each assistant spends at the copier is 5 minutes, which is equivalent to a service rate of 1/5 = 0.20 per minute. Use the M/M/1 model with a finite calling population to determine the following: The probability that the copier is idle. Round your answer to four decimal places. P0 = The average number of administrative assistants in the waiting line. Round your answer to four decimal places. Lq = The average number of administrative assistants at the copier. Round your answer to four decimal places. L = The average time an assistant spends waiting for the copier. Round your answer to four decimal places. Wq = min The average time an assistant spends at the copier. Round your answer to four decimal places. W = min During an 8-hour day, how many minutes does an assistant spend at the copier? How much of this time is waiting time? Round your answers to one decimal place. Time at Copier: minutes/day Wait time at Copier: minutes/day Should management consider purchasing a second copier? Explain. Round your answer to one decimal place. % of each administrative assistant's day is spent waiting for the copier.
