Answer the questions for the following table:

1. Using Table 1, the variance for activity E is

2. Using Table 1, the earliest start time for activity D is

3. Using Table 1, the earliest finish time for activity C is

4. Using Table 1, the critical path for the project consists of activities

5. Using Table 1, how much slack is associated with activity C

6. Using Table 1, the expected time to complete the project is

7. Using Table 1, the variance of the projects total completion time is approximately

8. Using Table 1, the probability that the project could be completed in 23 weeks or less is approximately

QUESTION 25 The following table of probabilistic time estimates (in weeks) and activity predecessors are provided for a project. \begin{tabular}{|l|l|l|l|l|} \hline Activity & optimistictime & mostlikelytime & pessimistictime & ActivityPredecessor \\ \hline A & 1 & 4 & 7 & \\ \hline B & 2 & 6 & 7 & \\ \hline C & 3 & 3 & 6 & B \\ \hline D & 6 & 13 & 14 & A \\ \hline E & 3 & 6 & 12 & A, C \\ \hline F & 6 & 8 & 16 & B \\ \hline G & 1 & 5 & 6 & E, F \\ \hline \end{tabular} Table 1 Reference: Ref 1
