- A.
0.665 to 0.95
- B.
At the most 0.665
- C.
At the most 0.95
- D.
At least 0.665
Attempted by 52 students.
Show answer & explanation
Correct answer: C
Reliability is estimated based on testing evidence and cannot exceed the observed probability of success during the test phase. Since only 70% of the code is covered, untested portions introduce uncertainty. Therefore, reliability cannot be claimed to be higher than the observed 0.95 success rate without further assumptions, making 'At most 0.95' the valid conservative upper bound.
