This set-up will continue through the next five questions, so be sure you are careful with your network development in this one. Recall that the project is finished when all tasks have been completed. Given the seven tasks below (T1 through T7), described in terms of their duration and predecessors, develop an activity-on-node diagram to answer questions 1 through 5. Duration, Task days Predecessors T1 8 T2 7 T1 T3 5 T1 T4 12 T2, T3 T5 5 T3 T6 7 T2, T3 T7 4 T5, T6 1. What is the minimum project duration in days? What is the critical path? T1-T3-T6-T7 T1-T2-T6-T7 T1-T2-T5-T7 T1-T3-T5-T7 T1-T3-T4 T1-T2-T4 How much slack (or float) does task T3 have, in days? If you crashed task T4 by two days, by how many days would you reduce the overall project duration? If you instead crashed task T6 by two days, by how many days would you reduce the overall project duration
