Based on the activity time estimates, the expected times and variance for each of the activities(A,B,C,D) are _______________________________ (round your response to two decimal places).

b) The expected completion time of the critical path =

(ans in 2 dp)

The expected completion time of the path other than the critical path =

C the variance of the critical path________

d) If the time to complete the activities on the critical path is normally distributed, what is the probability that this path will be finished in 22

weeks or less?

Compute Z.

(enter as a probability and round your response to two decimal places).

e) If the time to complete the activities on the non critical path is normally distributed, what is the probability that this path will be finished in

22 weeks or less?

Compute Z.

Using

Part 20

f) The smallest probability across all paths is the probability of project finishing in time.

Based on the probabilities found for the critical path and the other path, the probability that the project will be finished in 22 weeks or less =

Question 6, Problem 3.20 HW Score: 1.25%,0.25 of 20 Part 1 of 10 points Points: 0 of 2 The estimated times and immediate predecessors for the activities in a project at Howard Umrah's retinal scanning company are given in the following table. Assume that the activity times are independent. This exercise contains only parts a,b,c,d, and e. a) Based on the activity time estimates, the expected times and variance for each of the activities are (round your response to two decimal places)
