### Regression Analysis: House Size vs. Heating Bill

In this section, we will explore the regression output obtained from a simple linear regression analysis. The analysis investigates the relationship between the average winter heating bill (expressed in dollars) and the size of the house (expressed in square feet).

#### Summary Output
**Dependent Variable:** Heating Bill
**Independent Variable:** House Size

##### Regression Statistics

- **Multiple R:** Not Provided
- **R Square:** Not Provided
- **Adjusted R Square:** Not Provided
- **Standard Error:** Not Provided
- **Observations:** 10

##### ANOVA (Analysis of Variance)

The ANOVA table is used to ascertain the overall significance of the regression model.

|                | df | SS      | MS       | F     | Significance F  |
|----------------|----|---------|----------|-------|------------------|
| Regression     |    | 21369.9 | 21369.9  | 30.15 | 0.000579857      |
| Residual       |    | 5670.1  | 708.8    |       |                  |
| **Total**      |    |         |          |       |                  |

- **df (Degrees of Freedom):**
  - Regression: Not Provided
  - Residual: Not Provided
  - Total: Not Provided
- **SS (Sum of Squares):**
  - Regression: 21369.9
  - Residual: 5670.1
- **MS (Mean Square):**
  - Regression: 21369.9
  - Residual: 708.8
- **F (F-statistic):** 30.15
- **Significance F:** 0.000579857

##### Coefficients

The coefficients table provides the estimates of the regression coefficients, their standard errors, t-statistics, p-values, and confidence intervals.

|             | Coefficients | Standard Error | t Stat | P-value | Lower 95% | Upper 95% |
|-------------|--------------|----------------|--------|---------|-----------|-----------|
| **Intercept** | 24.81       | 55.48          | 0.447  | Not Provided | -114.57  | 164.18    |
| **House Size**| 0.085       | 0.0156         | 5.
