For the activity-on-arrow (AOA) network information given below: a. Construct an arrow diagram. b. On the diagram, compute the early and late event times (TE and TL) and event float (EF) for each node. Use event times to determine the four floats (TF, FF, INTF, INDF) for each activity. Identify the activities on the critical path and the project duration. Calculate and show results on the diagram in the following form: i TEXTL; EF Tij TFij , FFij INTFij, INDF; j TE TL; EF i j ACT Tij i i ACT Tij 2 4 A 3 18 22 M 10 2 6 B 4 18 24 N 6 4 8 dl 0 20 26 9 4 G 7 20 28 0 12 10 d4 d5 6 E 6 22 28 0 6 14 F 1 22 30 d6 0 8 12 3 24 30 8 10 12 d2 0 26 32 R 8 14 0 28 32 S 5 d3 H 12 16 2 28 34 T 6 14 18 J 5 30 34 V 2 16 20 K 3 32 36 3 16 22 L 4 34 36 W 9 For the activity-on-arrow (AOA) network information given below: a.
