**ANOVA Table Calculation and Interpretation**

This exercise involves calculating and interpreting an ANOVA (Analysis of Variance) table. Follow the steps below to complete the ANOVA table and determine the conclusion for the means of the three treatments.

1. **Sum of Squares Between Treatments (SST):**
   - Compute the sum of squares between treatments to the nearest whole number.

2. **Mean Square Between Treatments (MST):**
   - Compute the mean square between treatments to 1 decimal place.

3. **Sum of Squares Due to Error (SSE):**
   - Compute the sum of squares due to error to the nearest whole number.

4. **Mean Square Due to Error (MSE):**
   - Compute the mean square due to error to 1 decimal place.

5. **Setting Up ANOVA Table:**
   - Set up the ANOVA table for this problem. Round all Sum of Squares to the nearest whole number. Round all Mean Squares to 1 decimal place. Round F to 2 decimal places. Round your p-value to 4 decimal places.

   **ANOVA Table:**

   | Source of Variation | Sum of Squares | Degrees of Freedom | Mean Square | F     | p-value |
   |---------------------|----------------|--------------------|-------------|-------|---------|
   | Treatments          |                |                    |             |       |         |
   | Error               |                |                    |             |       |         |
   | Total               |                |                    |             |       |         |

6. **Testing for Significance:**
   - At the \( \alpha = 0.05 \) level of significance, test whether the means for the three treatments are equal.
   - Calculate the value of the test statistic to 2 decimal places.

   **The p-value is between 0.01 and 0.025.**

7. **Conclusion:**
   - Based on the p-value obtained and the significance level \( \alpha \), conclude whether the treatment means are equal or not.

To conclude correctly, if the p-value is less than the significance level \( \alpha \) (0.05 in this case), it means that there is a significant difference between the treatments. Hence, you would conclude that **not all treatment means are equal**.

**Partially Correct Interpretation:**

- The provided calculations and table setup need correctness verification as indicated by the incorrect marks (cross symbols).
