Q

Why would a specific test be used to RULE IN a hypothesis?

A

If the result is positive, it is likely that it is a TP - specific tests rule out FPs because the test has the ability to obtain a NEGATIVE result when it is a TN

Q

Why would a sensitive test be used to RULE OUT a hypothesis?

A

Sensitive tests have few FNs, so if a NEGATIVE result it obtained, it is likely that it is a TN - can rule out FNs
