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 modifyingabove potassium with caret equals 37 plus 26 fiberpotassium=37+26fiber. if your cereal provides 88 grams of fiber per​ serving, how much potassium does the model estimate you will​ get?

Answer 1

The produced regression model that correlates the amount fiber (in grams) and the potassium content (in milligrams) is:
potassium (mg) = 37 + 26 fiber (grams)
Considering that the cereal provides 88 grams of fibre per serving, the potassium in that same serving will be of 2325 milligrams (2,325 grams).
potassium (mg) = 37 + 26 × 88 ⇔ potassium (mg) = 2325
