Quizplus · Accepted Answer

To calculate the variance of the critical path, we need to find the sum of the variances of all critical activities. The critical activities are A-B-C-E-F-G, and their variances are 1+4+4+0+0+1=10. Therefore, the variance of the critical path is the square root of 10, which is approximately 3.16. Squaring this value gives us approximately 10, so the answer is (C) 9.
