Step 2 of 2: Determine if a statistically significant linear relationship exists between the independent and dependent variables at the 0.05 level of significance. If the relationship is statistically significant, identify the multiple regression equation that best fits the data, rounding the answers to three decimal places. Otherwise, indicate that there is not enough evidence to show that the relationship is statistically significant.

Question
The table titled "Effects on Selling Price of Houses" displays data on several factors influencing house prices. Each row represents a different house with the following columns:

- **Square Feet**: The total square footage of the house.
- **Number of Bedrooms**: The number of bedrooms in the property.
- **Age**: The age of the house in years.
- **Selling Price**: The selling price of the house in dollars.

Here is the data in the table:

| Square Feet | Number of Bedrooms | Age | Selling Price |
|-------------|---------------------|-----|---------------|
| 2683        | 3                   | 2   | 107,100       |
| 1889        | 4                   | 2   | 212,400       |
| 2602        | 4                   | 8   | 293,400       |
| 1905        | 3                   | 5   | 202,200       |
| 2851        | 4                   | 6   | 115,400       |
| 1916        | 5                   | 14  | 304,600       |
| 1920        | 2                   | 7   | 153,900       |
| 1634        | 3                   | 8   | 263,500       |
| 1258        | 4                   | 13  | 189,500       |

**Step 2 of 2**: This section discusses determining if there is a statistically significant linear relationship between the independent variables (square feet, number of bedrooms, and age) and the dependent variable (selling price) at a 0.05 level of significance.

- If the relationship is statistically significant, the task is to find the multiple regression equation that best fits the data, rounded to three decimal places.
- If not, it should be indicated that there is not enough evidence to show a statistically significant relationship.

There is a section provided to fill out the possible regression equation:
\[ \hat{y} = \text{(intercept)} + \text{(coefficient for square feet)} \times x_1 + \text{(coefficient for bedrooms)} \times x_2 + \text{(coefficient for age)} \times x_3 \]

There is also a checkbox option stating "There is not enough evidence" if the relationship is not significant.
