Explanation / Answer

Solution:

a) Students who are skipping class cannot be sampled.

Students who are on a school trip cannot be sampled

Students who are out sick cannot be sampled.

All the students who are skipping the class by any reason are ommited from the sample.

b) Home-schooled students cannot be sampled (true).

16-year-olds cannot be sampled. These statement "applies" (is true) because these students are too old to be in the study

These statements don't "apply" (are not true) because these people's names would still be on the school roster anyway:
Students who are out sick cannot be sampled. (false)
Students who are skipping class cannot be sampled. (false)
Students who are on a school trip cannot be sampled. (false)
