question 2 please

12:49 i need help with question 2 62 Use the network diagram to newer the questions below: 1. Determine ES. EF, LS. LP and lack for each activity. 2. What is the expected completion time for the project? 3. Find the critical path for the network 4. State the non-critical activities 5. Explain what it means an activity has a lot 6. Explain what it means if an activity has a sladkor QUESTION 2 On Blackboard, go to Apaments and print the Project Manage the table in problem 3.17, awer the following us *) Determine the expected time for each activity b) Determine the variance and standard deviation for each activity Using the critical path -------Kdermine the expected.com time for the project d) Determine the variance and standard deviation for the project What is the probability of completing the projectile than 10 weet What is the probability of completion of the project before we Question 2 ts Qumb focach btwity for canch Use the forman V = (ba) find the standard deviation for real activity @ronas Taller All t-values for atteity AC, F. 1.7, to Completion time anyt Project Variance = Add to voience of activity A, C, F, H, J,ak.
