WebbA project's critical path is composed of activities A (variance .33), B (variance .67), C (variance .33), and D (variance .17). What is the standard deviation on the critical path? … WebbThe standard deviation of the critical path is: A. 3. B. 5. C. 9. D. 16. E. 25. 72.There are four activities on the critical path. Coincidentally, their standard deviations are all equal to 4. The standard deviation of the critical path is therefore equal to: A. 2. B. 4. C. 8. D. 16. E. 64.

WebbThe standard deviation of the critical path of the project is Q. Consider the following PERT network: The optimistic time, most likely time and pessimistic time of all the activities are given in the table below: The standard deviation of the critical path is Q. In PERT analysis a critical activity has Q. WebbHere standard deviation is calculated for activities of critical path. So we get σ σ = V 1 + V 2 + V 3 = 1 + 4 + 1.778 = 2.6034 Now the probability of completion of project in that given time (t) of 26 days, can be calculate by below formula, Z = σt − tcp = 2.603426 − 24 = 0.7682 Using table in Appendix-B, we get probability = 77.8%
