Explanation
A is correct because the 1-Sample t-test is specifically designed to compare a single sample's mean against a known or hypothesized population value (the "target"), determining whether the observed sample mean differs significantly from that target.
B is incorrect - there is no distractor here beyond the false assertion itself; the statement in the question is a straightforward, accurate definition of the 1-Sample t-test's purpose.
Memory tip: Think "1 sample, 1 target" - the test has one group being measured against one fixed reference point. If you're comparing two samples to each other, that's a 2-Sample t-test; if you're comparing related pairs, that's a paired t-test. The "1-Sample" name literally tells you there's only one group, which means you must be comparing it to a predetermined value, not to another group.
