Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The cost level with an 80% confidence of being met or bettered.
Why this is correct
P80 is the standard benchmark for high-confidence budget estimation.
- ✗
The average cost of the project.
Why it's wrong here
Average is typically P50.
- ✗
The cost value representing the 20th percentile of risks.
Why it's wrong here
P80 is the 80th percentile of the total cost distribution.
- ✗
The baseline cost before risk adjustments.
Why it's wrong here
Baseline costs are usually fixed data points, not simulation percentiles.
