What distribution does cach of these time estimates follow? b) Find the critical path for the project. (Assume activity 1-2 starts at time o). c) Compute the expected value and the standard deviation of completion time for the critical path What distribution does this time estimate follow? d) The project contruct specifies that the project will be done in 30 days. What is the probability that this completion time will be achieved? Page 1 of 1 160 words IZ Accessibility: Unavailable 90% H Type here to search CH 29F Cloudy 3:24 PM 12/7/2021
