Answer to Problem 1E

  281 milligrams.

Explanation of Solution

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

  P^ otassium=38+27Fiber

Thus, if your cereal provides 9 grams of fiber per serving then the potassium the model estimate we will get is calculated as:

  P^ otassium=38+27Fiber=38+27×9=281

Thus, we have that 281 milligrams potassium is there if your cereal provides 9 grams of fiber per serving.
