What is the expected duration for the Project?

24.4

23.9

28.4

19.4

31.4

USE THE FOLLOWING Z values in your solutions. P(5) Z=-1.64 P(10) Z=-1.28 P(90) Z= +1.28 P(95) Z = +1.64 For the following questions, consider the project represented in the activity diagram below that represents the activities performed by the various engineers, programmers, and technicians of the controls engineering department to finish a project. The expected durations for each activity are listed in the first line of the activity node (e.g. "A,6" implies an expected activity duration of 6 months). The variances are listed in the second line of each activity node (e.g. 2^2 = 4 for Activity A). (Hint: You need only consider the critical path for these questions.)
