The probability of completing the project can be estimated based upon the _______.
- AUniform distribution curve
- BNormal distribution curveCorrect
- CU-shaped distribution curve
- DS-shaped distribution curve
Solution
Concept
PERT probability
Formula
Z = (Ts − Te)/σ
Step-by-step solution
1. PERT assumes the project duration is normally distributed. 2. Probability is found from the normal curve.
Explanation
The central limit theorem makes the sum of activity times normal.
Why the other options are wrong
Other shapes are not used.
Shortcut
Z-table.
Correct answer: B) Normal distribution curve
