Cereals For many people, breakfast cereal is an tant source of fiber in their diets. Cereals also contai potassium, a mineral shown to be associated with mei taining 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 = 38 + 27Fiber. If duced the linear model Potassium your cereal provides 9 grams of fiber per serving, how much potassium does the model estimate you will get? 7. Horsepower In Chapters 6's Exercise 36 we examined the relationship between the fuel economy (mpg) and horsepower for 15 models of cars. Further analysis pro- = 43.45 – 0.70HP. If the duces the linear model mpg - car you are thinking of buying has a 200-horsepower engine, what does this model suggest your gas mileage would be? 8. More cereal Exercise 6 describes a regression model that estimates a cereal's potassium content from the amount of fiber it contains. In this context, what does it mean to say that a cereal has a negative residual? 9. Horsepower again Exercise 7 describes a regression model that uses a car's horsepower to estimate its fuel economy. In this context, what does it mean to say that a certain car has a positive residual? 10. Another bowl In Exercise 6, the regression model = 38 + 27Fiber relates fiber (in grams) and Potassium potassium content (in milligrams) in servings of hreak-
