Answer

# Brief Explanations: The second sampling method includes 6th - 8th graders, covering a wider range of the population (all middle - school basketball players selling T - shirts). A wider and more inclusive sample is generally more representative. The first method only samples 7th - grade boys, which is a very narrow subset. # Answer: The second sampling method (6th–8th graders) is the most representative.
