3 Which of the following situations does NOT yield variability? I. How many grams of sugar are in a 12-ounce can of Dr. Pepper \( { }^{\circledR} \) ? II. How much sugar is used to make a gallon of punch? III. How many grams of sugar does a teenager consume each day? IV. How much sugar is in an 8 -ounce glass (A) I only (B) I and II only (C) II and III only (D) I and IV only

When considering variability, it’s important to identify how each situation expresses different amounts or quantities. In this case, options I (the specific sugar content in a can) and IV (the sugar content in an 8-ounce glass) both yield fixed values, meaning they do not introduce variability because each has a defined measurement. To break it down further, option II refers to a batch measurement that could vary depending on the recipe, and option III explores daily sugar consumption, which varies widely among individuals. Thus, the correct answer would be (D) I and IV only.
