\end{array}\end{array}$ What is the estimated expected (mean) time for activity E?
A) 31 weeks
B) 38 weeks
C) 39 weeks

E) 43 weeks

Question

Quizplus · Accepted Answer

The expected time (te) for an activity is calculated using the formula: te = (t0 + 4tm + tp) / 6. For activity E, te = (31 + 4*40 + 43) / 6 = 39 weeks.
