Chapter 2: Q12. (page 84)

For Exercises 10-12, use the graph that shows how much Americans spent on doctors’ visits in some recent years.
12. Compare your prediction to the one given in the graph.

Short Answer

Expert verified

The value predicted by the equation is lower than the given in the graph.

Step by step solution

Step-1 – Concept of prediction equation.

Prediction equation – An equation of line of fit is often called a prediction equation

Step-2 – Predicted value from the equation.

From the equation we know that the predicted value of amount spent on doctor’s visit $1077

And the actual value $1,172 from the graph.

$\begin{array}{l} 1172 - 1077 \\ = 95 \end{array}$

Step-3 – Compare the prediction.

The value predicted by the equation is lower than the given in the graph.
