Question

For many people, breakfast cereal is an important source of fiber in their diets. Cereals also contain potassium, a mineral shown to be associated with maintaining a healthy blood pressure. An analysis of the amount of fiber (in grams) and the potassium content (in milligrams) in servings of 77 breakfast cereals produced the regression model Potassium = 39 + 28Fiber. If your cereal provides 10 grams of fiber per serving, how much potassium does the model estimate you will get? milligrams of potassium

Explanation / Answer

Here we have given that the regression equation is,

Potassium = 39 + 28*Fiber

but we have given that Fiber = 10 grams and we have to find Potassium value.

Potassium = 39 + 28*10 = 39 + 280

Potassium = 319 milligram of potassium.
