1. **State the problem:** We are given a list of radio-controlled car prices: 115, 64, 31, 88, 99, 89, 149, 55, 23, 67.
We need to find the Median, Mode, and Range of these prices.
2. **Median:** The median is the middle value when the data is ordered from least to greatest.
Order the data: 23, 31, 55, 64, 67, 88, 89, 99, 115, 149.
Since there are 10 values (even number), the median is the average of the 5th and 6th values.
$$\text{Median} = \frac{67 + 88}{2} = \frac{155}{2} = 87.5$$
3. **Mode:** The mode is the value that appears most frequently.
Check frequencies: all values appear once, so there is no mode.
4. **Range:** The range is the difference between the maximum and minimum values.
$$\text{Range} = 149 - 23 = 126$$
**Final answers:**
- Median: 87.5
- Mode: No mode
- Range: 126
Median Mode Range 067De1
