A team uses sequential testing for the criterion "98% accuracy with ±4% at a 95% CL", and the observed accuracy consistently remains at 98% or more. When can testing stop, approximately?
1 answer is correct. Hard
Show answer
Answer
- B After about 170 test cases
Explanation
In sequential testing, results are evaluated as you go, and you stop as soon as the evidence is sufficient. If the measured accuracy stays at 98% or more throughout, the required precision of ±4% at 95% CL is already reached after about 170 cases.
