Problem $1(1\mathrm{.}5$ points$)$

Using the information presented in the following table, identify the processing sequence that would result using $(1)$ FCFS$,(2)$ SPT$,$ and $(3)$ DD rules. For each method, determine $(1)$ average flow time, $(2)$ average job lateness, and $(3)$ average number of jobs at the work center. Jobs are listed in order of arrival. $($Hint: First determine the total job time for each job by computing the total processing time for the job and then adding in the setup time. All times and due dates are in hours.$)$
