a. Draw a network diagram for the activities. b. Calculate the earliest start and finish time. c. Calculate the latest start and finish time. d. Show the critical path. Explain why it is the critical path? e. What would happen if activity F were revised to take six weeks instead of two weeis? 3. Consider the same project description given in question 2. Assume that your team is in the first week of the project and has discovered that each of the activity duration estimates is wrone. Activity B will take only 2 weeks to complete. Activities D and 6 will each take three times longer than anticipated. All other activities will take twice as long to complete as previously estimated. In addition, a new activity K has been added. it will take one week to complete, and its immediate predecessors are activities I and I. Adjust the network diagram and recalculate the earliest and latest completion times. is there any change to the critical path? a. Draw a network diagram for the activities. b. Calculate the earliest start and finish time. c. Calculate the latest start and finish time. d. Show the critical path. Explain why it is the critical path
