**ANOVA Table for a Multiple Regression Model**

The following table presents an ANOVA (Analysis of Variance) for a multiple regression model. The table includes columns for Source, degrees of freedom (df), Sum of Squares (SS), Mean Square (MS), and the F-statistic (F).

| Source | df | SS | MS | F |
|-------------|-----|-----|-----|---|
| Regression | 3 | 375 | 125 | 5 |
| Residual | 20 | 500 | 25 | |
| Total | 23 | 875 | | |

**Question:**

a. What is the size of this sample?

$ n = \square $

To find the sample size, note that the total degrees of freedom $ df_{\text{Total}} $ is 23. The sample size $ n $ can be calculated as $ n = df_{\text{Total}} + 1 = 23 + 1 = 24 $.
