### Educational Website – Analysis of Poplar Tree Weights and Bonferroni Results

#### Statistical Hypothesis Testing for Poplar Weights

**Objective:**
To determine if different treatments affect the mean weight of poplar trees.

**Significance Level:**
0.10

**Hypotheses:**
- **Null Hypothesis (H₀):** μ₁ = μ₂ = μ₃ = μ₄ (The mean weights are equal across all treatments).
- **Alternative Hypothesis (H₁):** At least one mean is different.

**Instructions:**
1. **Test Statistic:** Calculate and round to two decimal places.
2. **P-value:** Calculate and round to three decimal places.

**Conclusion Options:**
- **A:** Fail to reject H₀. Sufficient evidence to reject that treatments yield the same mean weight.
- **B:** Fail to reject H₀. Insufficient evidence to reject that treatments yield the same mean weight.
- **C:** Reject H₀. Insufficient evidence to reject that treatments yield the same mean weight.
- **D:** Reject H₀. Sufficient evidence to reject that treatments yield the same mean weight.

#### Interpretation of Bonferroni Results

**Graphical Table Explanation:**
- **Table Content:**
  - Treatment groups: No Treatment, Fertilizer, Irrigation, Fertilizer and Irrigation.
  - Recorded weights for each treatment.

- **Bonferroni Results:**
  - Mean differences between treatments (I-J).
  - Standard Error.
  - Significance (Sig.) values, used to determine if differences are statistically significant.

**Bonferroni Analysis Review:**
- Evaluate if the mean differences are statistically significant by looking at the Sig. value.
- A significance value below 0.10 indicates a significant difference between treatment means.

**Next Step:**
Examine how these results inform decision-making about the effectiveness of different treatments on the weight of poplar trees.
