The estimated regression equation for a model involving two independent variables and 10 observations follows:

\[
\hat{y} = 33.0798 + 0.6071x_1 + 0.7058x_2
\]

**a. Interpret \(b_1\) and \(b_2\) in this estimated regression equation (to 4 decimals).**

- \(b_1 =\) (input box)

(Selection menu for interpretation)

Options:
- \(y\) changes by 0.6071 when \(x_1\) increases by 1 unit and \(x_2\) stays the same
- \(y\) changes by 0.6071 when \(x_2\) increases by 1 unit and \(x_1\) stays the same
- \(y\) changes by 0.7058 when \(x_1\) increases by 1 unit and \(x_2\) stays the same
- \(y\) changes by 0.7058 when \(x_2\) increases by 1 unit and \(x_1\) stays the same

- \(b_2 =\) (input box)

### Explanation:

This regression equation involves two independent variables, \(x_1\) and \(x_2\). The coefficients \(b_1\) and \(b_2\) represent the expected change in the dependent variable \(y\) for a one-unit increase in each respective independent variable, holding the other variable constant. The given options allow selection for correct interpretation of these coefficients.
