1. Consider a project that has been modeled as in Table 1. Table 1: Activities and Predecessors Activity Immediate Predecessors. Duration B D A A B.C B.C D.E 6 3 12 E F 14 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 0 A = 2. 0g = 1. c = 0, Op = 2, E = 3, and op = 0. 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 PL-15 25 +1] 68%, PT-2
