2) You want to examine competition in barnacles. You examine two species and count the number of each species at the low and high water marks (many barnacles live in tidal areas). You get the following results: Low water High water Species A Species B 63 13 21 54 (a) Are the two species of barnacle independent of water level? (b) Which species prefers low water? Which prefers high water?

**Examining Competition in Barnacles**

You are studying the competition between two species of barnacles. The examination involves counting the number of each species at the low and high water marks, as many barnacles live in tidal areas. The results are as follows:

|           | Low Water | High Water |
|-----------|-----------|------------|
| Species A | 63        | 13         |
| Species B | 21        | 54         |

**Questions:**

(a) Are the two species of barnacle independent of water level?

(b) Which species prefers low water? Which prefers high water?

**Explanation:**

This data represents the distribution of two barnacle species at different tidal marks. By comparing the numbers, it is possible to assess their preference for water levels and whether their distribution is independent of these levels.
