I need help with the following: -Calculating the expected time and variance for all of these activities.-Drawing the full network with the Activity on Node Style. -Calculate what the Criticial Path is using CPM method. -Activity variance for the critical path and the standard deviation -Finding the probability of completing of the project before 41 weeks using the Simple Way ### Project Schedule Estimation TableThis table provides time estimates for various project activities, classified under three categories: optimistic, most likely, and pessimistic scenarios. The table helps in planning and managing timelines effectively.#### Table Components- **Activity**: The identifier for each task within the project.- **Immediate Predecessor(s)**: Activities that must be completed before the current activity can start.- **Time Estimates (in Weeks)**: - **Optimistic**: The shortest estimated completion time if everything proceeds better than expected. - **Most Likely**: The most probable estimated time under normal circumstances. - **Pessimistic**: The longest estimated time considering possible delays.#### Activities Breakdown- **Activity A** - No immediate predecessors - Time Estimates: Optimistic (4), Most Likely (8), Pessimistic (10)- **Activity B** - Predecessor: A - Time Estimates: Optimistic (2), Most Likely (8), Pessimistic (24)- **Activity C** - Predecessor: A - Time Estimates: Optimistic (8), Most Likely (12), Pessimistic (16)- **Activity D** - Predecessor: A - Time Estimates: Optimistic (4), Most Likely (6), Pessimistic (10)- **Activity E** - Predecessor: B - Time Estimates: Optimistic (1), Most Likely (2), Pessimistic (3)- **Activity F** - Predecessors: E, C - Time Estimates: Optimistic (6), Most Likely (8), Pessimistic (20)- **Activity G** - Predecessors: E, C - Time Estimates: Optimistic (2), Most Likely (3), Pessimistic (4)- **Activity H** - Predecessor: F - Time Estimates: Optimistic (2), Most Likely (2), Pessimistic (2)- **Activity I** - Predecessor: F - Time Estimates: Optimistic (6), Most Likely (6), Pessimistic (6)- **Activity J** - Predecessors: D, G, H - Time Estimates: Optimistic (4),

A critical path can be described as a series of tasks that need to be completed in order for a project to succeed. It is also called critical chain management. The main idea behind this approach is that all the tasks are important, but some are more important than others and should, therefore, be given more attention.activity a m b Te=(a+4m+b)/6 Variance=((b-a)/6)^2 A 4 8 10 7.666666667 1 B 2 8 24 9.666666667 13.44444444 C 8 12 16 12 1.777777778 D 4 6 10 6.333333333 1 E 1 2 3 2 0.111111111 F 6 8 20 9.666666667 5.444444444 G 2 3 4 3 0.111111111 H 2 2 2 2 0 I 6 6 6 6 0 J 4 6 12 6.666666667 1.777777778 K 2 2 3 2.166666667 0.027777778
