A given project activity has the following time estimates: 08 b=33 m = 19 What is the variance o? ) of this project activity's estimated duration? (Round to 2 decimal places) s Suppose a project's critical path consists of three activities, each with duration estimates as follows Activity Pessimistic (b) X Duration Estimates (days) Optimistic (a) Most Likely (m) 6 17 8 19 10 18 32 29 Y IZ 31 What is the standard deviation of this project's expected completion time? (Round to 2 decimal places) To answer this question you will need to use the standard normal table presented below... A project's critical path has an expected duration of 62 days with a standard deviation of 7 days. If we wanted to promise a completion time that we'd be 65.54% sure we could live up to, what should that promised completion time be?
