1. In a project analysis using three time estimates with more than one critical path existing, how does the project manager decide which variances to use in arriving at the probability of meeting the project due date? *

1 point

a. The project manager averages the variances and uses that

b. The project manager uses the smallest variance in order to get the highest probability of on-time completion

c. The project manager uses the variances considered most correct

d. The project manager uses the largest variances in order to understate the probability of on-time completion

2. Which of the following is a wrong description about three time estimates? *

1 point

a. Optimistic time is the minimun reasonable period of time in which the activity can be completed.

b. Most likely timeis the random guess of the time required.

c. Pessimistic time is the maximum reasonable period of time the activity would take to be completed.

d. An important feature of using three time estimates is that it can be used to evaluate the effect of uncertainty on project completeion time.

3. How to calculate the expected time for each acvity with three time estimates? *

1 point

a. ET=(a+m+b)/3

b. ET=(a+4m+b)/3

c. ET=(a+4m+b)/6

d. ET=(b-a)2/6
