Each of the 5 cats in a pet store was weighed. Here are their weights (in pounds):
```
13, 12, 5, 12, 9
```
#### Task:
Find the median and mean weights of these cats. If necessary, round your answers to the nearest tenth.
**Calculation:**
1. **Median:**
- Organize the weights in ascending order: 5, 9, 12, 12, 13
- The median is the middle number in the ordered list.
- Since there are 5 weights, the median is the 3rd value.
- **Median Weight:** 12 pounds.
2. **Mean:**
- Add all the weights together: \( 13 + 12 + 5 + 12 + 9 = 51 \)
- Divide by the number of cats: \( \frac{51}{5} = 10.2 \)
- **Mean Weight:** 10.2 pounds.
#### Answers:
(a) Median: `12` pounds
(b) Mean: `10.2` pounds
