To calculate the relative frequency, we need to know two things:

1. The frequency of each age group (provided in the frequency column).
2. The total number of students in the group, which is the sum of all frequencies.

The relative frequency for each age group is given by the formula:

$\text{Relative Frequency} = \frac{\text{Frequency of the Age Group}}{\text{Total Frequency}}$

If you can provide the frequency table or the data, I’ll be able to calculate the relative frequencies for you. Feel free to upload the table!
