Document Summary
Short answer - quiz a: the advertising campaign for a high fibre cereal wants to claim that high fibre cereals are lower in calories. Describe the association between fibre and calories: comment on any unusual data point or points in the data set. At first glance, there appears to be a weak, negative association between grams of fibre and the number of calories in the cereals. The points with 9, 10 and 14 grams of fibre appear to have an unusually high amount of fibre for their calorie content, making them outliers and influential points. It would be extrapolation to try to use this data to predict the calorie content of cereals with 22 grams of fibre.
