Activity Immediate Activity Time Predecessor (days) D 11 B 9 C D 12 D 18 A 3 C G C, D 19 H B, E 2 - H N C F, G, I 6 Total = 86 You can see the project network below. After detailed analysis of the project, you found the expected activity times (in days) for all ten activities. These numbers are incorporated into the project network.

(b) The critical path is select an answer . If you get more than one critical path, please select the upper one. For example, if you have A-C-G-J and B-H-I-J, then you have to select A-C-G-J. (c) The expected optimal completion time is E(t) = days. (d) Based on the results for the questions (a)-(b), answer the following questions: . How many days the activity C can be delayed without increasing the expected project completion time? . Is it possible that the activity A is delayed without increasing the expected project completion time? Select an answer (e) The following table shows the calculated expected variance for each activity.

Round the result to 2 decimal places. (T) - days (f) Assume that the project completion times are normally distributed with / = E(t) (see question (c)) and o = o(T) (see question (d)). What is the probability that the project will be completed in . 59 days? P(T
