The manager of a National Forest is about to undertake a reforestation project in a burned out area.The project will involve the following six activities:  What is the estimated expected (mean)duration for project completion?
A)135 days 
B)145 days 
C)170 days 
D)180 days 
E)255 days

Quizplus · Accepted Answer

To find the expected duration, we need to add up the expected durations of all six activities. This gives us:

(EA + 4EB + 3EC + 3ED + 2EE + EF) = (5 + (4*6) + (3*10) + (3*6) + (2*16) + 20) = 107

Therefore, the estimated expected duration for project completion is 107 days. The closest answer choice is C, which is 170 days.
