Perform a schedule risk analysis for the Technology Refresh Project (Version B) by completing the following:

Open the attached "Project Risk Assessment Problems Template." Take note of the project information, including the expected durations and the tasks that are on the critical path.

Calculate the following:

1. The expected project finish time.

2. The variances for the applicable tasks.

3. The total critical path variance.

4. The total critical path standard deviation.

The customer has seen the Technology Refresh (Version B) Project schedule and the expected project finish time. However, the customer is concerned about the schedule risk of the project. Therefore, he wishes to know the following (i.e., determine the following):

5. The probability of finishing the project in 287 days.

6. The probability of finishing the project in 273 days.

Hint: Before answering the questions, review the "PERT Variance and Probability of Project Completion" video, located in the Topic 4 Resources.

7. Note also that Microsoft Excel's NORM.DIST function can be used to determine the probabilities of finishing, which does not require the use of the Z-table.

Please provide formulas.
