Aproject is composed of the following activities: immediate activity predecessor days a — 4 b — 9 c a 3 d b 8 e b 7 f d 2 g e 5 (a) draw the project network and compute the earliest start, latest start, earliest finish, and latest finish time for each activity. (b) how long will it take to complete the project? (c) what is the critical path? (d) compute the slack for each of the non-critical activities. (e) if activity a were to be delayed and takes three days longer than planned, by how much would the project be delayed? (f) if the time to complete activity b were to be reduced by one day, how much sooner would the project be completed? (g) if the time to complete activity e were to be reduced by three days, how much sooner would the project be completed?
