$(4)$ Perform a project management analysis for the data given below to determine ES$,$ EF$,$ LS$,$ LF$,$ and slack for each activity, the total project completion time, and the critical path.

$($a$)$ Draw a network with $\backslash ($ t$,$ E S$,$ E F$,$ L S $\backslash ),$ and $\backslash ($ L F $\backslash )($follow the same format as Figure II$\mathrm{.}5$ on p$\mathrm{.}394).$

$($b$)$ Complete the following table $($similar in format to Table $/1.3$ on p$\mathrm{.}396).$

$($c$)$ Identify the critical path$($s$)$:

$($d$)$ Based on your analysis, the project completion time is:

weeks and the least critical activity is:
