61. The critical path for the network shown is:
62. The slack for path A-D-H-I is:
E. 8.
Given this network:
16–15
71. There are four activities on the critical path, and they have standard deviations of 1, 2, 4,
and 2 days. The standard deviation of the critical path is:
72. There are four activities on the critical path.Coincidentally, their standard deviations are
all equal to 4. The standard deviation of the critical path is therefore equal to:
(time in days)

(time in days)
78. What is the estimated mean time for activity E?
79. What is the estimated standard deviation in the time for activity E?
80. What is the estimated mean time for project completion?
