Explanation:

To determine the most fair way to collect data (i.e., a representative sample), we need to check which option has an equal number of people surveyed in each age group (since we want to survey 40 people total and have 4 age groups).

Step 1: Calculate total for each option

  • Option A: \( 5 + 30 + 2 + 3 = 40 \), but the numbers are not equal across groups.
  • Option B: \( 10 + 15 + 5 + 10 = 40 \), numbers are not equal.
  • Option C: \( 10 + 5 + 15 + 10 = 40 \), numbers are not equal.
  • Option D: \( 10 + 10 + 10 + 10 = 40 \), each age group has 10 people, which is equal (representative sampling, as each group is equally represented).

Answer:

D. 10, 10, 10, 10
