Short Answer

How can a 2% measured error rate constrain the best possible error rate?

Question: Answer in one to three sentences using the performance of the inspection committee.

Sample answer: Because the inspection committee has already shown that it can reach a 2% error rate, any benchmark based on human performance must be at least that strong. So the best possible error rate cannot be greater than 2%, even though a lower value is still possible.

Key points:

  • A 2% error rate has been achieved in practice.
  • Observed performance sets an upper limit on the best achievable error.
  • The true optimum may still be below 2%.

Rubric: The answer must explain that a demonstrated 2% error rate means the optimal error rate cannot exceed 2% and could be lower.
