Question
In this problem, we are given a multiple regression equation and asked to find the value of \( x_2 \) given specific values for \( x_1 \) and \( \hat{y} \).

The regression equation is:

\[
\hat{y} = 127 + 8x_1 + 18x_2
\]

We need to calculate the value of \( x_2 \) when \( x_1 = 12.5 \) and \( \hat{y} = 443 \).

**Calculation:**

Substitute \( x_1 = 12.5 \) and \( \hat{y} = 443 \) into the equation:

\[
443 = 127 + 8(12.5) + 18x_2
\]

Solve for \( x_2 \).
