###### Question:

Huang’s television-repair service receives an average of 8 TV sets per 8-hour day to be repaired. The service manager would like to be able to tell customers that they can expect their TV back in 5 days.

What average repair time per set will the repair shop have to achieve to provide 5-day service on the average? (Assume that the arrival rate is Poisson distributed and repair times are exponentially distributed.)
