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 = 37 + 27fiber. if your cereal provides 8 grams of fiber per serving, how much potassium does the model estimate you will get?

milligrams of potassium

Explanation:

Step1: Substitute the value of fiber into the regression model

Given the regression model \( \text{Potassium}=37 + 27\times\text{Fiber}\), and the fiber content \( \text{Fiber} = 8\) grams.
Substitute \( \text{Fiber}=8\) into the equation: \( \text{Potassium}=37+27\times8\).

Step2: Calculate the value of potassium

First, calculate \( 27\times8 = 216\).
Then, calculate \( 37+216\).
\(37 + 216=253\).

Answer:

253
