1. Create an activity on arrow diagram based on the following information:

Task A, duration 6, dependent on none

Task B, duration 5, dependent on none

Task C, duration 3, dependent on none

Task D, duration 12, dependent on Task B and TaskC

Task E, duration 2, dependent on Task A

Task F, duration 5, dependent on Task B

Task G, duration 1, dependent on Task B

Task H, duration 9, dependent on Task E and TaskF

Task I, duration 7, dependent on Task G

Task J, duration 7, dependent on Task H

Task K, duration 3, dependent on Task I

Task L, duration 5, dependent on Task D

Using the diagram you created in question 1, calculate early start ES, early finish EF, late start LS, and late finish LF for each task and the amount of slack. List the tasks that appear on the critical path
