To find the median investment for the 17 towns shown in the scatter plot, you must identify the middle value (the 9th point) when the data is ordered along the horizontal axis ( $x$-axis), which represents the money invested.
1. Identify the Median Position
Since there are $\(\mathbf{1 7}\)$ towns in total, the median is the value in the middle position:
$$
\(\text { Median Position }=\frac{n+1}{2}=\frac{17+1}{2}=9 \text { th town }\)
$$
2. Count the Data Points along the X-Axis
Counting from left to right (from the lowest investment to the highest), we locate the 9th point:
1. 23k: 1 point
2. 30k: 1 point
3. 31k: 1 point
4. 33k: 1 point
5. 37k: 1 point
6. 38k: 1 point
7. 40k: 1 point
8. 42k : There are 2 points at this vertical grid line. These represent the 8th and 9th points.
The 9th point falls exactly on the grid line for 42.
3. Conclusion
The value on the horizontal axis for the 9th point is $\(\mathbf{4 2}\)$. Since the axis is labeled "in thousands," the median amount is $\(\mathbf{\$ 4 2 , 0 0 0}\)$.
Correct Answer: $42,000
