associated Z score is 2.33. Target completion time = 9 + 2.33 * 1.41 = 12.2853 = 12.3 weeks If given 12.3 weeks to complete the project, the project manager would be 99% confident of completing the project on time. It is logical to focus on the variability of the critical activities because they are the more important activities in the project network. However, it is also important to investigate the variability of activities on the noncritical path. The variability in noncritical activities with large variances should be closely monitored. For a project, Z was calculated as 0.35, the probability of the target completion is __________. 63% 63.31%
63.68% or 64% 35% The target completion time for a project with an expected completion time of 13 weeks and project standard deviation of 1.15 is __________ with a 90% certainty. 14.0 weeks 14.5 weeks o r (13 + 1.28 * 1.15) weeks 13.5 weeks 16.4 weeks PERT makes the assumption that __________. the activity times are statistically dependent the total project completion times do not follow a normal probability distribution the total project completion times follow a normal probability distribution the activity times follow a normal probability distribution The variance of the complete project is computed by summing the variances of the activities on the __________. project critical path noncritical path project network Given the following activities for a project, with the critical activities in red, the project standard deviation is __________. √(0.22 + 0.36 + 1.00) o r 1.97 1.26 √(0.22 + 0.25 0.36) √0.22 + √0.25 + √1.00 The bell-shaped normal curve represents the project completion dates, and there is a 50% chance of completing __________ the expected completion. on around prior to, after near Given the following activities for a project, with the critical activities in red, the project variance is __________.
