Using the above table to tabulate all results, determine the following:

a$.$ Expected Activity times $(2$ points$)$

b$.$ Activity Variances $(2$ points$)$

c$.$ Redraw the network in order to determine the earliest and latest start and finish times $(1$ point$)$

d$.$ LS$,$ ES$,$ LF$,$ EF for each activity $(4$ points$)$

e$.$ Slack for each activity $(2$ points$)$

f$.$ Identify the critical path $(1$ point$)$

g$.$ Project duration $(1$ point$)$

h$.$ Project variance $(1$ points$)$

i$.$ Project standard deviation $(1$ points$)$
