I don't get why the answer to this is a No. I thought it would be "Yes". What am I missing?

Given: Half of the students in Jaime’s class is on the volleyball team, and all of the students in Jaime’s class make up half of the students in the school.

Is it inferable that the one quarter of the students in the school are on the volleyball team?

We know that AT LEAST one quarter of the students in the school are on the volleyball team.

1/4 of the school is both in J's class and on the volleyball team.

But it's possible that people who AREN'T in J's class are ALSO on the volleyball team, so it's possible that more than 1/4 of the students are on the volleyball team.

Oh wow, that was quite tricky! Thank you for clarifying.

Thanks for explaining Patrick, makes sense when you put it like that.
