A large number of cold breakfast cereals were studied for a consumer magazine study. Variables identified in the table below include: the name of the cereal, the number of calories per serving, the number of grams of fat per serving, the number of milligrams of sodium per serving, the number of grams of dietary fiber per serving, the number of grams of carbohydrates per serving, the number of grams of sugar per serving, and the display shelf on which the cereal was found most frequently in supermarkets, as well as a health rating given by nutritionists.
The display shelf codes are: B (bottom shelf), M (middle shelf), and T (top shelf).
The health ratings span values from: 1 (most unhealthy), and 100 (healthiest).
In the sortable table below, click on the column title to organize the table by that column's values.
The table above can be sorted to decide whether the following statements are true or false, based on the scenario above.
Cereals on the bottom shelf have the highest mean amount of sugar per serving as compared with the other shelves.
The range of health ratings for fat-free cereals is greater than the range of health ratings for cereals that contain some fat.
One gram of fat contains about 9 calories. Using this standard, less than one quarter of the cereals listed in the table have fat accounting for at least 15% of their calories.
