Final answer:
1) Yes, we can rule it in
A test with a .95 specificity, when the result is positive, can be ruled in.
Step-by-step explanation:
The question is asking if we can rule in or out a test with a .95 specificity when the test result is positive. In this scenario, we can rule it in.
A test with a specificity of .95 means that 95% of the time, the test correctly identifies negative cases. However, this leaves a 5% chance of a false positive result. Even though there is a small chance of a false positive, a positive result from the test still provides evidence in favor of the condition being tested for.
Therefore, option 1) Yes, we can rule it in is the correct answer.
