Given the data below are the number of students in each age group.

Ages	Number of students
15-18	3
19-22	7
23-26	2
27-30	5
31-34	2
35-38	4
Based on the frequency distribution above, find the relative frequency for the class with lower class limit 27. Give your answer as a percent, rounded to one decimal place.

Relative Frequency =  %

To calculate the relative frequency for the class with the lower class limit of 27 (which corresponds to the age group 27-30), you can use the following steps:

### Step 1: Calculate the total number of students.
Add up the number of students in all age groups:

\[
\text{Total number of students} = 3 + 7 + 2 + 5 + 2 + 4 = 23
\]

### Step 2: Determine the number of students in the age group 27-30.
From the table, the number of students in the age group 27-30 is 5.

### Step 3: Calculate the relative frequency.
Relative frequency is calculated as:

\[
\text{Relative Frequency} = \left(\frac{\text{Number of students in the age group}}{\text{Total number of students}}\right) \times 100\%
\]

Substitute the values:

\[
\text{Relative Frequency} = \left(\frac{5}{23}\right) \times 100\% \approx 21.7\%
\]

So, the relative frequency for the class with the lower class limit 27 is **21.7%**.
