Approximately what percentage of the total sample indicates that Hip-Hop is…

Concept: When a table breaks a total sample into categories, the percentage that one category contributes to the whole sample equals (sum of that category’s own row across every group ÷ sum of every value in the entire table) × 100, rounded to the nearest whole percentage.

1. Add every entry in the Hip-Hop row across all three age groups: 9 + 3 + 4 = 16.

2. Add every entry in the table to get the total sample size, using the three age-group column totals: Age 15-20 column = 6+7+6+1+2+9+2 = 33; Age 21-30 column = 4+5+12+4+3+3+2 = 33; Age 31+ column = 17+5+14+11+15+4+2 = 68. Grand total = 33 + 33 + 68 = 134.

3. Apply the percentage formula: (16 ÷ 134) × 100 = 11.94%.

4. Round to the nearest whole percentage as the question instructs: 12%.

Cross-check: Summing each style’s own row instead of each age group’s column gives the same grand total — Classical 27, Pop 17, Rock 32, Jazz 16, Blues 20, Hip-Hop 16, Ambient 6 — which add to 134, confirming the total used above.

So approximately 12% of the total sample indicates Hip-Hop as their favourite style of music.
