### Example Problem: Finding Median and Mean Weights

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
