Question: In a conformance test for Radio transmission and reception (TDD), what are the pass criteria based on the total number of successful tests and the associated confidence level?
Option 1: More than 80% success rate with a confidence level of 90%
Option 2: Exactly 95% success rate with a confidence level of 99%
Option 3: At least 75% success rate with no specified confidence level
Option 4: More than 90% success rate with a confidence level of 95%
Explanation: This answer reflects the stringent requirements for ensuring reliability and performance in wireless communications, balancing high success rates with a statistically significant confidence level, to ensure devices meet rigorous transmission and reception standards while allowing for minor tolerances.
