1. Draw the Activity on Arrow (AOA) diagram and calculate ES, EF, LS, LF, TF, and FF for each activity. Show the detailed calculation FF for each successor activities. Identify the critical activities and paths and answer the following question. (30 Points) a. If activity F is delayed by 2 days, will it delay total duration of the project and the start date of successor activities? If yes, then by how many days the total duration will be delayed and why? Which successor activity's start date will be delayed and by how many days and why? For Free Float (FF) Calculation of the Activity which has more than one successor activities, you need to add the rows or show me the FF calculation separately below the table.
