Jawaban:

B. 18 siswa

Penjelasan:

Total nilai murid-murid = 6+7+8+9+9+7+10+8+9+9+7+7+8+8+7+8+9+9+5+9+6+7+5+9+10+7+9+9+9+6 = 236

Mean/nilai rata-rata

= Total nilai/jumlah murid

= 236/30 = 7,86

Jumlah murid dengan nilai di atas rata-rata = 18 (No. 3, 4, 5, 7, 8, 9, 10, 13, 14, 16, 17, 18, 20, 24, 25, 27, 28, dan 29)

Semoga jawabannya membantu ^__^
