To solve the problem, we need the regression equation from question 19. Since we don't have question 19 available in the image, we'll need to know the regression equation to predict $y$ when $x = 12$.

The general form of a simple linear regression equation is: $y = a + bx$ where:

• $y$ is the dependent variable (the value we want to predict),
• $x$ is the independent variable (the given value, which is 12 in this case),
• $a$ is the y-intercept, and
• $b$ is the slope of the regression line.

If you can provide the regression equation from question 19, I can help you calculate the predicted value of $y$ for $x = 12$.

Would you like to provide the regression equation or need assistance with another question?
