Answer

Brief Explanations:

The sample of ten random samples from 75 students is better. Larger and more random samples are generally more representative. The first sample of 5 students in her homeroom is small and non - random (only from homeroom), while the second sample is larger and random from the whole club.

Answer:

The ten random samples from the 75 - student drama club are a better representation because they are larger and more randomly selected compared to the small, non - random sample of 5 students from her homeroom.
