A machine shop runs two lathes to machine parts. Each lathe is capable of machining 5 parts per hour on average. There are eight parts, on average are arriving at the machine shop. 1. If all arriving parts wait in the common line for the next available machine, how long would a part in the line before machining. 2. The shop manager decided that 50 percent of the arriving parts be machined by one machine (machine A) and remaining 50 percent of the parts by another machine (Machine B). How long would a part in the line before machined by machine A. 3. Do you observe difference in answers in wait time from question a and b. If so, why? Explain
