Consider Table 6-2. All duration estimates or estimated times are in days, and the network proceeds from Node 1 to Node 9. 

Data from in Table 6-2

a. Draw an AOA network diagram representing the project. Put the node numbers in circles and draw arrows from node to node, labeling each arrow with the activity letter and estimated time.
b. Identify all of the paths on the network diagram and note how long they are, using Figure 6-8 as a guide for how to represent each path.
c. What is the critical path for this project and how long is it?
d. What is the shortest possible time needed to complete this project?
