1. Using the three-point task time estimates, what is the expected duration of task A?

2. Using the three-point task time estimates, what is the expected duration of task E?

3. What is the expected project duration?

4. What is the variance(sigma squared) of the time estimates for task A?

5. What is the variance(sigma squared) for the project duration?

6. What is the standard deviation(sigma or square root of sigma squared) for the project duration?

7. What is the z-value for a scheduled project duration of 42 days? (round your answer to two decimal places. If negative, insert a negative sign preceding your value. Example -.1026 = -.10)

8. What is the probability of completing the project in 42 days or less?
