Consider the following table containing yields for mutual funds in different asset classes (small, mid, and large cap).


Based on the table provided and the question regarding the sum of squares for treatments and errors, the problem relates to **ANOVA (Analysis of Variance)**.

### Degrees of Freedom (DF)
1. **Degrees of Freedom for Treatments (DF₁):**
   The degrees of freedom for treatments is calculated as the number of groups (k) minus 1.
   - From the table, we can see three categories: **Small Cap**, **Mid Cap**, and **Large Cap**. Thus, there are **3 groups**.
   \[
   \text{DF}_{\text{treatments}} = k - 1 = 3 - 1 = 2
   \]

2. **Degrees of Freedom for Error (DF₂):**
   The degrees of freedom for the error is calculated as the total number of observations (N) minus the number of groups (k).
   - To find the total number of observations (N), count all the entries in the table. There are **8** small-cap funds, **8** mid-cap funds, and **7** large-cap funds. So:
   \[
   N = 8 + 8 + 7 = 23
   \]
   \[
   \text{DF}_{\text{error}} = N - k = 23 - 3 = 20
   \]

Thus, the degrees of freedom are:
- **DF for treatments = 2**
- **DF for error = 20**
