Chapter 8, Problem 5E

To determine

To explain what the slope means.

Explanation of Solution

In the previous question it is given that, an analysis of the amount of fiber in grams and the potassium content in milligrams in serving of breakfast produced the regression model:

  $\text{<mover accent="true"><mo>P</mo><mo>^</mo></mover> otassium}=38+27\text{Fiber}$

Thus, the slope of $27$ indicates that a one gram increase in the fiber content leads to a $27$ milligrams increase in the potassium content.
