Options

A. 37
B. 17
C. 27
D. 27.5

Answer

To find the range of the given data set, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Data Set**:
The data provided is: 25, 15, 23, 40, 27, 25, 23, and 42.

2. **Find the Maximum Value**:
Look through the data set to find the largest number.
- The maximum value is **42**.

3. **Find the Minimum Value**:
Look through the data set to find the smallest number.
- The minimum value is **15**.

4. **Calculate the Range**:
Use the formula for range, which is:
\[ \text{Range} = \text{Maximum Value} - \text{Minimum Value} \]
Substitute the values we found:
\[ \text{Range} = 42 - 15 \]

5. **Perform the Calculation**:
Now, calculate the result:
\[ \text{Range} = 27 \]

### Final Answer:
The range of the data is **27**.
