Answer

Explanation:

Step1: Calculate total number of students

$9 + 2+2 + 6+10 + 7=36$

Step2: Calculate relative frequency of the class 15 - 18

Relative frequency = $\frac{\text{Frequency of 15 - 18 class}}{\text{Total number of students}}\times100%=\frac{9}{36}\times 100%$ $\frac{9}{36}\times 100% = 25.0%$

Answer:

$25.0$
