Activity Immediate Predecessor Duration, weeks

A $-3$

B A $4$

C A $2$

D B$,$ C $6$

E C $5$

F C $3$

G E $7$

H E$,$ F $5$

I D$,$ G$,$ H $8$

Find the early start time $($EST$),$ early completion time $($ECT$),$ late completion time $($LCT$),$ early completion time $($ECT$)$ and slack of each activity. Plug only the resulting numbers into the following table. Pay attention to the column names!
