1. Consider a project that has been modeled as in Table 1. Table 1: Activities and Predecessors Activity Immediate Predecessors Duration A 7 B A 6 3 D B,C 12 E B,C 14 F DE 5 a. Draw the PERT/CPM network for this project and determine the project's expected completion time up and its critical path. b. Suppose the standard deviations of the activity durations are a = 1, B 1, 0, op = 1,08 = 2, and de 1. Then please estimate the standard deviation of the overall project's standard deviation op. c. Suppose for the standard Normal random variable 2, we know P[-13 ZS +1) 68%, PI-2 323 +21 - 95%, and PC-3 S2 S +3] 99.7%. Then, approximately what time T is one for which there is only a less than 16% chance for the completion time to beat (be shorter than)
