Answer

Brief Explanations:

Adriana's sample is too small and limited to friends at her lunch - table. Henry's sample only includes boys in his homeroom, which is a non - representative subset. Malik's sample only includes students using an MP3 player while waiting for the bus, a biased group. Richard samples from 12 classes in an alphabetical way, which is more likely to be a representative sample of all seventh - graders.
