Jika diagram batang di bawah ini memperlihatkan frekuensi kumulatif hasil tes matematika siswa kelas XII, maka persentase siswa yang memperoleh nilai 8 adalah..... A. 12% B. 15% C. 20% D. 22% E. 80%

<p>Jawaban: A</p><p>&nbsp;</p><p>Konsep:</p><p>Persentase yang ditanya = jumlah nilai yang ditanya/jumlah total × 100%</p><p>&nbsp;</p><p>Pembahasan:</p><p>Nilai | Frekuensi | Frekuensi Kumulatif</p><p>&nbsp; &nbsp;2 &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp;1 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 1</p><p>&nbsp; 3 &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; 2 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 3</p><p>&nbsp; 4 &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; 3 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 6</p><p>&nbsp; 5 &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; 4 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 10</p><p>&nbsp; 6 &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; 5 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 15</p><p>&nbsp; 7 &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; 4 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 19</p><p>&nbsp; 8 &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; 3 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 22</p><p>&nbsp; 9 &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; 2 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 24</p><p>10 &nbsp; &nbsp;| &nbsp; &nbsp; &nbsp; &nbsp; 1 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; | &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 25</p><p>&nbsp;</p><p>Maka persentase siswa yang memperoleh nilai 8:</p><p>3/25 × 100% = 12%</p><p>&nbsp;</p><p>Jadi, persentase siswa yang memperoleh nilai 8 adalah 12%.</p><p>Oleh karena itu, jawaban yang benar adalah A.</p>
