A CPM/PERT project network with probabilistic activity times includes an activity with a most likely time of 17 days, an optimistic time of 8 days, and a pessimistic time of 26 days. The mean time for this activity is  (round to the nearest whole number)

A PERT/CPM activity has an optimistic time estimate of 5 days, a most likely time estimate of 10 days, and a pessimistic time estimate of 24 days. What is the expected time (in days) of this activity?Round answer to two decimal places.hint: formula is available in lecture notes

For an activity in a CPM analysis, the early finish time is 12 and the late finish time is 12. Which of the following statements is true? Group of answer choicesThe duration of this activity is 12.The late start is 12.The early start is 12.The activity could be on the critical path.The slack for this activity is 12.

If the most pessimistic and most optimistic estimates of the amount of time needed to complete an activity are 10 days and 4 days, respectively, the activity's variation is expected to bea.1b.2c.3d.4
