### Relative Frequencies of Grade ClassesA frequency table of grades has five classes (A, B, C, D, F) with frequencies of 2, 14, 15, 8, and 3 respectively. Using percentages, what are the relative frequencies of the five classes?**Complete the table below:**| Grade | Frequency | Relative Frequency (%) ||-------|-----------|------------------------|| A | 2 | || B | 14 | || C | 15 | || D | 8 | || F | 3 | |*(Round to two decimal places as needed.)*### Instructions to Calculate Relative Frequency:1. **Determine the Total Frequency:** Add the frequencies of all the classes. \[ \text{Total Frequency} = 2 + 14 + 15 + 8 + 3 = 42 \] 2. **Calculate the Relative Frequency for Each Class:** - For Grade A: \[ \frac{2}{42} \times 100 = 4.76\% \] - For Grade B: \[ \frac{14}{42} \times 100 = 33.33\% \] - For Grade C: \[ \frac{15}{42} \times 100 = 35.71\% \] - For Grade D: \[ \frac{8}{42} \times 100 = 19.05\% \] - For Grade F: \[ \frac{3}{42} \times 100 = 7.14\% \]Update the table with the calculated relative frequencies:| Grade | Frequency | Relative Frequency (%) ||-------|-----------|------------------------|| A | 2 | 4.76 || B | 14 | 33.33 || C | 15 | 35.71 || D | 8 | 19.05 || F | 3 | 7.14 |
