Suppose you calculated the mean and the standard deviation of the critical path (longest path) as mean = 100 days, standard deviation as 10 days. The mean and the standard deviation of the second longest path are 95 and 12 days, respectively. Which of the following statements is true?
I. The second longest path can be longer than the critical path
II. Simulation and PERT would give very similar answers for the 90th percentile of the project duration
III. PERT bias would be insignificant (negligible) for this problem
a) I
b) II
c) III
d) II & III
e) None of them is correct
