Question
To create a frequency table for the set of exam scores provided, we will utilize 5-point bins (e.g., 95 to 99, 90 to 94, etc.). We will include columns for frequency, relative frequency, and cumulative frequency.

### Given Exam Scores:
70, 91, 73, 80, 99, 85, 78, 72, 78, 90, 74, 94, 80, 88, 70, 99, 95, 95, 99, 71

### Step-by-Step Process:

1. **Determine the Frequency:**
   - Tally how many scores fall into each 5-point bin.
   
2. **Calculate the Relative Frequency:**
   - The relative frequency is calculated as (Frequency / Total Number of Scores) * 100%.
   
3. **Compute the Cumulative Frequency:**
   - The cumulative frequency is the running total of the frequencies, starting from the lowest bin to the highest.

### Frequency Table:
Complete the table below by filling in each column based on the given scores.

**Scores | Frequency | Relative Frequency (%) | Cumulative Frequency**
--- | --- | --- | ---
95 to 99 |  |  | 
90 to 94 |  |  | 
85 to 89 |  |  | 
80 to 84 |  |  | 
75 to 79 |  |  | 
70 to 74 |  |  | 
**Total** | **20** | **100%** |

### Explanation of the Table:

- **Scores:** Represents the range of scores in each bin.
- **Frequency:** The number of data points (scores) that fall within each bin.
- **Relative Frequency:** The percentage of the total data points that fall within each bin.
- **Cumulative Frequency:** The sum of the frequencies for the current bin and all previous bins.

### Completing the Table:

- **Calculate Frequencies:**
  - 95 to 99: Scores = [99, 99, 99, 95, 95], Frequency = 5
  - 90 to 94: Scores = [91, 90, 94], Frequency = 3
  - 85 to 89: Scores = [85, 88], Frequency = 2
  - 80 to 84: Scores = [80, 80], Frequency =
