Answer

Explanation:

Step1: Calculate relative - frequency of 7th graders present

Relative frequency = $\frac{\text{Number of 7th - graders present}}{\text{Total number of 7th - graders}}$ Relative frequency = $\frac{44}{48}=\frac{11}{12}\approx0.9167$

Step2: Calculate relative - frequency of all absent students

Relative frequency = $\frac{\text{Total number of absent students}}{\text{Total number of students}}$ Relative frequency = $\frac{11}{120}\approx0.0917 = 9.17%\approx9%$

Answer:

The relative frequency of 7th graders who are present is $\frac{11}{12}$; The relative frequency of all students who are absent is 9%
