The CPM/PERT network for a project with probabilistic activity times has a mean project completion time of 54 days, with a standard deviation of 6 days. What is the probability that the project will be completed in 44 days or less? (Answer to 4 decimal places.) (There's a normal distribution table in the associated PDF file that you can print out and use to answer this question.) Question 26 1pts The CPM/PERT network for a project with probabilistic activity times has a mean project completion time of 55 days, with a standard deviation of 4 days. What is the probability that the project will be completed in 61 days or less? (Answer to 4 decimal places.) (There's a normal distribution table in the associated PDF file that you can print out and use to answer this question.) Question 27 1pts A PERT/CPM activity has an optimistic time estimate of 1 days, a most likely time estimate of 5 days, and a pessimistic time estimate of 18 days. The expected time (in days) of this activity is: (Report the answer to 2 decimal places.)
