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 = 38+26*fiber. if your cereal provides 8 grams of fiber per serving, how much potassium does the model estimate you will get?

Explanation:

Step1: Identify the regression - model formula

The regression model is Potassium = 38+26*Fiber.

Step2: Substitute the fiber value

Given fiber = 8 grams. Substitute fiber = 8 into the equation: Potassium = 38+26×8.

Step3: Perform the multiplication

26×8 = 208. So the equation becomes Potassium = 38 + 208.

Step4: Perform the addition

38+208 = 246.

Answer:

246 milligrams
