+394 An experiment was planned to determine the effect of fertilizer on a measure of leaf area. A number of plots were available for the study, and half were selected at random to be fertilized. In order to assure that the plots to receive the fertilizer and the control plots were similar prior to beginning the experiment, tree density (the number of trees per hectare) was recorded for eight plots to be fertilized and eight control plots, resulting in the given data.
| **Fertilizer plots** | 1024 | 1216 | 1312 | 1280 | 1216 | 1312 | 992 | 1120 |
|-----------------------|------|------|------|------|------|------|-----|------|
| **Control plots** | 1104 | 1072 | 1088 | 1328 | 1376 | 1280 | 1120 | 1200 |
**Question:**
Based on this data, would you conclude that there is a significant difference in the mean tree density for fertilizer and control plots? Use \( \alpha = 0.05 \).
**Answer Options:**
1. **Fail to reject H₀:** There is not sufficient evidence to conclude that there is a difference in the mean tree density for fertilizer and control plots.
2. **Reject H₀:** There is sufficient evidence to conclude that there is a difference in the mean tree density for fertilizer and control plots.
