If the contracted duration for a project with the following network is 120 days, what is the probability (in percent) of meeting the schedule based on PERT analysis? Then, assume that the owner delays the start by 5 days while keeping the end date as originally scheduled. What is the probability (in percent) that the project will still finish at the originally scheduled completion date? The requested probabilities should be determined based on the entire network and not just one path.
Please assume that the provided pessimistic and optimistic values in the problem are based on 99 percentile level. Please show work for at least one instance of each calculation, that is, show work for:
- one set of calculation of the mean, standard deviation and variance at activity level
- one set of calculation of the mean, standard deviation and variance at the path level
- calculation of probability
The network does not need to be reproduced in the submission.

It was determined on the following project that the duration for the tasks contained some uncertainty. After more research, the optimistic and pessimistic values were determined. 1. a. Calculate the expected time and variance (using the 95 percent level of confidence) for each activity. b. Determine the critical path and time for completion c. Calculate the probably that the project will finish in 30 days. Calculate the probably of completing the project in 27 days. Other than the critical path,...

1. State whether each of the following statement is true or false. a) The sequence of activities in a project is depicted by the precedence (0.5 mark) (0.5 mark) relationships. The critical path is the shortest path through the project network. Slack is the amount of time an activity can be delayed without delaying the project. In PERT, three time estimates (optimistic, most likely and pessimistic) provide an estimate of the mean and variance for each activity based on the...
