all those students walking on campus late at night.

Explanation:

In statistics (a subfield of Mathematics), a sample is the subset of the population that is actually studied. Here, the reporter interviews 15 students (the ones willing to give opinion and met late at night). The sample is these 15 interviewed students. The other options: "all students approached" includes those who didn't give opinion, "all students at universities with safety issues" is not relevant to Ohio State, and "all students walking late" is the population of interest's subgroup but the sample is the 15 interviewed.

Answer:

the 15 students interviewed.
