To find the median temperature of the pond, we first need to arrange the temperatures in ascending order, which they already are:
- 65°F
- 67°F
- 69°F
- 71°F
- 73°F
- 75°F
Since there are 6 temperatures (an even number), the median will be the average of the two middle numbers. The middle numbers in this case are the 3rd and 4th numbers:
- 3rd number: 69°F
- 4th number: 71°F
Now, we can calculate the median:
\[ \text{Median} = \frac{69 + 71}{2} = \frac{140}{2} = 70°F \]
Therefore, the median temperature of the pond is 70°F.
