a$)$ Fill in the table with each path and show your work by calculating the time for each path in the table to determine the critical $($longest$)$ path$($s$).$ Add$/$delete rows in the table as needed. You must indicate the critical path and the estimated project completion time below the table.

$\backslash$table$[[$Path$,$Time$],[,],[,],[,],[,],[,],[,],[,]]$

Critical Path $=$

Estimated Project Completion $=$

b$)$ Fill in the ES & EF times in the table below working from Start to Finish. Then, fill in the LS & LF times working backwards from Finish to Start. After determining the ES$,$ EF$,$ LS$,$ & LF times, calculate the Slack time for each activity using both Slack $=LS-ES$ and Slack $=LF-EF.$ Note: Both calculations must give you the same answers.

$\backslash$table$[[$Activity$,$ES$,$EF$,$LS$,$LF$,$Slack$],[$A$,,,,,],[$B$,,,,,],[$C$,,,,,],[$D$,,,,,],[$E$,,,,,],[$F$,,,,,],[$G$,,,,,],[$H$,,,,,]]$
