Complete the table below:
![**Grade Distribution and Frequency Table for Business Statistics Exam**
The table below presents the distribution of grades for a Business Statistics Exam. The grades are categorized from A to F, based on the numerical score ranges, and the corresponding frequencies and relative frequencies are provided.
| Grade | Range | Frequency | Relative Frequency |
|-------|---------|-----------|-------------------|
| A | 90 - 100| [ ]| 0.07 |
| B | 80 - 89| 34 | [ ]|
| C | 70 - 79| 94 | [ ]|
| D | 60 - 69| 36 | [ ]|
| F | 60 below| 22 | [ ]|
| Total | | 200 | 1.0 |
### Analysis:
1. **Grade Ranges:**
- Grade A: Scores between 90 and 100
- Grade B: Scores between 80 and 89
- Grade C: Scores between 70 and 79
- Grade D: Scores between 60 and 69
- Grade F: Scores below 60
2. **Frequency and Relative Frequency:**
- The Frequency column indicates the number of students who received each grade.
- The Relative Frequency column shows the proportion of students receiving each grade relative to the total number of students (200), with a total relative frequency value of 1.0.
- The relative frequency for Grade A is provided as 0.07. The remaining values for other grades must be calculated based on the given frequencies and the total number of students (200).
### Calculation of Missing Values:
- To fill in the missing relative frequencies, use the formula:
\[
\text{Relative Frequency} = \frac{\text{Frequency}}{\text{Total Number of Students}}
\]
- Calculate for Grade B as follows:
\[
\text{Relative Frequency for B} = \frac{34}{200} = 0.17
\]
- Calculate for Grade C as follows:
\[
\text{Relative Frequency for C} = \frac{94}{200} = 0.47
\]
