Answer 1

To create a frequency table for the given data using the specified ranges, we will count how many values fall into each range.

The data set is:
3, 12, 25, 2, 3, 6, 17, 17, 15, 13, 20, 12, 21, 18, 19.

Let’s count the values for each range:

- **Range 1 – 5**: 2, 3, 3 → **3 values**
- **Range 6 – 10**: 6 → **1 value**
- **Range 11 – 15**: 12, 12, 13, 15 → **4 values**
- **Range 16 – 20**: 17, 17, 18, 19, 20 → **5 values**
- **Range 21 – 25**: 21, 25 → **2 values**

Now, we can summarize this in a frequency table:

| Range | Number of Values |
|-----------|------------------|
| 1 – 5 | 3 |
| 6 – 10 | 1 |
| 11 – 15 | 4 |
| 16 – 20 | 5 |
| 21 – 25 | 2 |

Based on the counts, the value that should be placed in the second column for the range 1 – 5 is **3**.
