Explanation:

A representative sample should be unbiased and reflect the diversity of the population. Randomly choosing 3 people from each of 10 blocks spreads the sample across the neighborhood. Randomly choosing from a neighborhood - association mailing list also gives a random selection from the overall population. Choosing only families with small children is biased as it doesn't represent all neighbors.

Answer:

• Ruben randomly chooses 3 people from each of the 10 blocks in his neighborhood.
• Ruben asks his neighborhood association for their mailing list. Then, he randomly chooses 30 people from that list.
