total project completion time $($in days$)$ and those activities that lie along the critical path. The appropriate data are shown in the following table:

$\backslash$table$[[,$Time $($days$),$Immediate,,Time $($days$),$Immediate$],[$Activity$,a,m,b,$Predecessor$($s$),$Activity,$a,m,b,$Predecessor$($s$)],[$A$,4,6,7,-,$H$,4,4,6,$E$,$ F$],[$B$,1,2,3,-,$I,$1,6,8,$G$,$ H$],[$C$,6,6,6,$A$,$J$,2,5,7,$I$],[$D$,5,8,11,$A$,$K$,8,9,11,$I$],[$E$,1,9,18,$B$,$ C$,$L$,2,4,6,$J$],[$F$,2,3,6,$D$,$M$,1,2,3,$K$],[$G$,1,7,8,$D$,$N$,6,8,10,$L$,$ M$]]$

a$)$ The expected completion time of the project $=57\mathrm{.}56$ days $($round your response to two decimal places$).$

The activities that represent the project's critical path are

c$)$ Using the tandard normal table, the number of days that would result in $99\%$ probability of completion $=$ days $($round your response to two decimal places$).$
