### Simulated Escape Exercise for Offshore Oil Workers

A sample of 26 offshore oil workers took part in a simulated escape exercise. The accompanying data represent the time taken (in seconds) for each worker to complete the escape. The data is presented using a stem-and-leaf plot.

#### Stem-and-Leaf Plot of Escape Time Data

The stem-and-leaf plot below shows the time taken (in seconds) for each offshore oil worker to complete the escape exercise:

```
Stem | Leaf
--------|------
32 | 55
33 | 49
34 |
35 | 6699
36 | 4469
37 | 03345
38 | 2
39 | 2347
40 | 23
41 |
42 | 1
```

#### Explanation of the Stem-and-Leaf Plot

- Each "stem" represents the leading digits of the escape times.
- Each "leaf" represents the trailing digit of the escape times.
- For instance, a leaf of 55 on the stem 32 represents an escape time of 325 seconds.
- Similarly, a leaf of 1 on the stem 42 represents an escape time of 421 seconds.

This plot helps to visually organize and summarize the escape times, making it easier to identify patterns and outliers in the data.
