1. **State the problem:** We have a data set representing the number of states traveled to or lived in:
$$1, 5, 6, 2, 6, 1, 12, 7, 1, 2, 6, 1, 2, 9, 13$$
We need to find the median, mode, and range of this data (Question 9), and then determine if changing the value 5 to 8 affects the median (Question 10).
2. **Recall definitions and formulas:**
- Median: The middle value when data is ordered.
- Mode: The most frequently occurring value.
- Range: Difference between the maximum and minimum values.
3. **Find the median, mode, and range for the original data:**
- Order the data:
$$1, 1, 1, 1, 2, 2, 2, 5, 6, 6, 6, 7, 9, 12, 13$$
- Median: Since there are 15 numbers (odd), median is the 8th value:
$$\text{Median} = 5$$
- Mode: The value appearing most often is 1 (appears 4 times).
- Range: $$13 - 1 = 12$$
4. **Answer for Question 9:**
Median = 5, Mode = 1, Range = 12
5. **For Question 10, update the data by changing 5 to 8:**
New data:
$$1, 8, 6, 2, 6, 1, 12, 7, 1, 2, 6, 1, 2, 9, 13$$
Order the new data:
$$1, 1, 1, 1, 2, 2, 2, 6, 6, 6, 7, 8, 9, 12, 13$$
Median is the 8th value:
$$\text{Median} = 6$$
6. **Conclusion:**
Yes, the median increases from 5 to 6.
**Final answers:**
9. Median = 5, Mode = 1, Range = 12
10. A. Yes. It increases to 6
Median Mode Range 608A4B
