Jack's managers would like to determine the total project completion time (in days) and these activities that lie along the critical path. The appropriate data are shown in the following table Time (days) Immediate Time (days) Immediate Activity a Predecessor(s) Activity Predecessors) A 4 5 9 3 3 8 EF B 1 2 10 GH 5 A 9 D 6 11 A K 8 13 1 E 3 10 17 BC L 2 5 8 J F 2 3 7 D M 2 3 3 G 3 10 D N 7 7 12 LM a) The expected completion time of the project days (Round your response to do decimal places) The activities that represent the project's criticni pottare b) if the time to complete the activities on the critical path is normally distributed, then the probability that the critical path will be finished in 55 days or less - Round your response to two decimal places) c) Number of days that would result in % probability of completion = days. (Round your response to two decimal places)
