1.) Draw the network using the table above. Make sure all 4 values (ES, EF, LS, LF) are listed on the network. 2.) What is the slack for each activity? What is the critical path? Show ALL of your work! 3.) Find the expected project completion time. What is the project variance?

2.) What is the slack for each activity? What is the critical path? Show ALL of your work!
3.) Find the expected project completion time. What is the project variance?
4.) What is the probability that it would be in more than 14 days? Show ALL of your work.

I'm still confused on the ES,EF, LS, LF part can you explain it a bit more, how do I calculate for slack?. The excel sheet is a bit confusing to understand for that specific part
