Daive Fletcher was able to determine the activity tirnos for constructing his laser scanning machine, Flotcher would like to determine ES, EF, LS, LF, and slack for each activity. The total project cornpletion fime and the critical path should also bo dotermined Here are the activity times: Dave's earliest start (ES) and oadiest firish (EF) are \begin{tabular}{ccc} Activity & ES & EF \\ \hline A & 0 & 5 \\ B & 0 & 8 \\ C & 5 & 8 \\ D & 5 & 6 \\ E & 8 & 13 \\ F & 8 & 15 \\ G & 15 & 23 \\ H & 13 & 21 \end{tabular} \begin{tabular}{ccc} \hline Activity & LS & LF \\ \hline H & 17 & 23 \\ G & 13 & 23 \\ F & 10 & 17 \\ E & 8 & 13 \\ D & 16 & 17 \\ C & 10 & 13 \\ B & 0 & 1 \\ A & 5 & 10 \end{tabular} Ine slack times are: Enter your answer in each of the answer boxes
