The table below shows the distribution of petal length in two populations (A and B) of the same plant species. Each population was sampled from a different habitat.
| Petal length (mm) | Number of individuals in Population A | Number of individuals in Population B |
|---|---|---|
| 22–24 | 0 | 12 |
| 24–26 | 2 | 45 |
| 26–28 | 8 | 30 |
| 28–30 | 35 | 10 |
| 30–32 | 62 | 8 |
| 32–34 | 38 | 10 |
| 34–36 | 5 | 32 |
| 36–38 | 1 | 48 |
| 38–40 | 0 | 15 |
