Answer

Brief Explanations:

To get a representative sample for the average practice - hours of sixth - graders at his school, the sample should be from sixth - graders at his school. Surveying only boys, only band students, or friends from the neighborhood is not representative. Randomly surveying 50 sixth - graders at his school targets the correct population.

Answer:

He can randomly survey 50 sixth - graders in the school.
