(a) Fill in the activity nodes. (b) The critical path is |A-E-H-I-J v . 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) = 19 days. (d) Based on the results for the questions (a)-(b), answer the following questions: . How many days the activity B can be delayed without increasing the expected project completion time? . Is it possible that the activity H is delayed without increasing the expected project completion time? No, it is not possible. v
