### Activity Network for Project Management### Construction of PERT Network:To effectively manage a project and understand the sequence of activities and their dependencies, a Program Evaluation Review Technique (PERT) network is essential. Below is the list of activities and their immediate predecessors, which form the foundation for drawing the PERT network.#### Activity and Immediate Predecessor(s):```| Activity | Immediate Predecessor(s) ||----------|--------------------------|| A | - || B | A || C | A || D | B || E | B || F | C || G | D || H | E, F |```### Explanation:1. **Activity A** has no immediate predecessors, meaning it is the starting point of the project.2. **Activity B** can only start after Activity A is completed.3. **Activity C** also depends on the completion of Activity A.4. **Activity D** requires Activity B to be finished before it can be initiated.5. **Activity E** like Activity D, depends on the completion of Activity B.6. **Activity F** can only start after Activity C is completed.7. **Activity G** requires Activity D to be completed.8. **Activity H** can only start after both Activities E and F are completed.### How to Draw the PERT Network:1. **Start Node**: Begin with the initiation node representing the start of Activity A.2. **Nodes and Arrows**: - Draw an arrow from the start node to a node representing Activity A. - From Activity A, draw arrows leading to two separate nodes: B and C. - From B, draw arrows leading to two separate nodes: D and E. - From C, draw an arrow leading to a node for Activity F. - From D, draw an arrow leading to a node for Activity G. - Finally, draw arrows from both E and F, leading to a final node representing Activity H.3. **End Node**: Mark the end node after Activity H completion.The resulting diagram should visually encapsulate the dependencies as listed and allow one to visually sequence and plan the project efficiently.

Can someone help me with the following problems on excel. Thank you
Recently, you were assigned to manage a project for your company. You have constructed a network diagram depicting the various activities in the project (shown below to the right). In addition, you have asked your team to estimate the amount of time that they would expect each of the activities to take. Their responses are shown in the following table: Time Estimates (days) Activity Optimistic Most Likely A 4 B 3 C D E 4 1 3 8 7 5 4 8 Pessimistic 12 10 8 5 9 Start A B E Finish a. What is the expected completion time of the project? The expected completion time is 19 days. (Enter your response as an integer.) b. What is the probability of completing the project in 21 days? Refer to the standard normal table. The probability of completing the project in 21 days is N (Enter your response rounded to four decimal places.)

Consider the typical road network of Figure 1. It rep- resents an area of downtown Jacksonville, Florida. The streets are all one-way, with the arrows indicating the di- rection of traffic flow. The flow of traffic in and out of the network is measured in terms of vehicles per hour (vph). The figures given here are based on midweek peak traffic hours, 7 A.M. to 9 A.M. and 4 P.M. to 6 P.M. An increase of 2 percent in the overall flow should be al- lowed for during the Friday evening traffic flow. Let us construct a mathematical model that can be used to ana- lyze this network. 400 vph 800 vph 225 vph Hogan Street> 5 Duval Street Monroe Street 250 vph Figure 1 Downtown Jacksonville, Florida B Laura Street 350 vph 125 vph 300 vph 600 vph
