Explanation:

To get a representative sample of the number of hours the average sixth - grader at his school practices an instrument each week, the sample should be from the target population (sixth - graders at his school). Surveying only boys, only school band students, or friends from the neighborhood are biased samples. Randomly surveying 50 sixth - graders in the school targets the correct population.

Answer:

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