Which statement is not true about global operations? A. To attract and retain global talent, and to expand a product's life cycle, are both reasons to globalize. B. One reason to globalize is to learn to improve operations. C. Production processes are being dispersed to take advantage of national differences in labour costs. D. Ford's partnerships with GM is an example of a response to the global environment. E. One reason for global operations is to gain improvements in the supply chain. A contractor's project being analyzed by PERT has an estimated time for the critical path of 133 days. The sum of all activity variances is 57; the sum of variances along the critical path is 47. The probability that the project will take 151 or more days to complete is A. 0.996 B. 0.009 C. 0.649 D. 0.351 E. 0.004 Question 12 of 100 1 Points An activity on a PERT network has these time estimates: optimistic = 12, most likely = 10, and pessimistic = 5. Its expected time is A. 4.5 B. 27 C. 9.5 D. 9 E. 52.833 Which of the following statements is false about PERT/CPM techniques? A. PERT technique uses three duration estimates for each activity in order to best determine the activity's estimated duration. B. The standard deviation of a project duration is equal to the sum of the variances of all the activities of the project. C. In PERT technique, the activity time distribution is assumed to be a beta distribution. D. For the PERT/CPM technique, completing the backward pass includes making the latest finish (LF) equal to the earliest finish (EF) for the end activity. E. Consecutive activities on the same path have shared slack, which means if activities are delayed, the amount of slack remaining is reduced for all these activities without delaying ompletion of the project
