To solve this problem, we need to calculate the relative frequencies for each class. Relative frequency is calculated by dividing the frequency of each class by the total frequency and then converting that fraction to a percentage.

Step 1: Determine the Total Frequency

The total frequency is the sum of all the individual frequencies.

$\text{Total Frequency} = 5 + 13 + 13 + 7 + 1 = 39$

Step 2: Calculate the Relative Frequency for Each Class

Relative frequency for each class is calculated as follows:

$\text{Relative Frequency} = \left(\frac{\text{Frequency of Class}}{\text{Total Frequency}}\right) \times 100$

1. Class A: $\text{Relative Frequency} = \left(\frac{5}{39}\right) \times 100 = 12.82\%$
2. Class B: $\text{Relative Frequency} = \left(\frac{13}{39}\right) \times 100 = 33.33\%$
3. Class C: $\text{Relative Frequency} = \left(\frac{13}{39}\right) \times 100 = 33.33\%$
4. Class D: $\text{Relative Frequency} = \left(\frac{7}{39}\right) \times 100 = 17.95\%$
5. Class F: $\text{Relative Frequency} = \left(\frac{1}{39}\right) \times 100 = 2.56\%$

Step 3: Enter the Relative Frequencies in the Table

So the completed table will be:

• Class A: 12.82%
• Class B: 33.33%
• Class C: 33.33%
• Class D: 17.95%
• Class F: 2.56%
