Based on the calculations from part (b), we can see that the SJF scheduling algorithm has the lowest average waiting time of all the algorithms, with an average waiting time of 6.75 time units. Therefore, SJF scheduling results in minimal average waiting time for these set of processes.

This result is not surprising as SJF scheduling algorithm tends to prioritize short processes over longer ones, which leads to a lower average waiting time overall. However, SJF scheduling can also suffer from starvation if there are longer processes constantly arriving in the system, as the shorter processes may keep being selected first and the longer processes may never get a chance to execute.

Therefore, it is important to choose the scheduling algorithm that is appropriate for the specific workload characteristics and system requirements. For example, if the system needs to prioritize certain types of processes or ensure a certain _____ ________ __________ _________ _________ ___ _________ ____ _________ _________ _________.
