Question
**Find the standard deviation for the group of data items.**

Below is a stem-and-leaf plot:

| Stems | Leaves |
|-------|--------|
| 0     | 8      |
| 1     | 5 8    |
| 2     | 5 8    |

**Explanation of the table:**

- The "Stems" column represents the leading digit(s) of each data point.
- The "Leaves" column lists the trailing digit(s) that complete the data values.
- Therefore, the data points are: 8, 15, 18, 25, and 28.

**Task:**

Calculate the standard deviation of these data points. \( \text{(Round to two decimal places as needed.)} \)

The standard deviation is \( \_\_\_ \).
