Question 5: Shown are the probabilistic activity time estimates for the CPM/PERT network:

For all results, arrange data (in table format like below) to calculate the following:

1. Expected Times for each activity
2. Each Activity Variances
3. Every activity: LS, ES, LF, EF (when figuring out the latest and earliest finish times, redraw the network)
4. Every activity: Slack

Activity	Time estimates			Expected Time	Activity Variance	Latest Start Time (LS)	Earliest Start Time (ES)	Latest Finish Time (LF)	Earliest Finish Time (EF)	Slack
	a	m	b
1	1	2	6
2	1	3	5
3	3	5	10
4	3	6	14
5	2	4	9
6	2	3	7
7	1	2	3
8	1	3	5
