Answer

There is a positive correlation between height and weight because taller women tend to weigh more.

Solution

1. **Identify the Variables:** - Let \( H \) be the height of a female between ages 1 and 21. - Let \( W \) be the weight of a female between ages 1 and 21. 2. **Determine the Relationship:** - In general, as individuals grow taller, they tend to have a larger body mass. Therefore, when height increases, weight generally increases. - This indicates a direct (or positive) relationship between the two variables. 3. **Correlation Explanation:** - A positive correlation means that as one variable increases, the other variable also increases. - In this context, since taller females are expected to weigh more, the correlation is positive. 4. **Conclusion:** - The correct answer is **B. Positive correlation because taller women tend to weigh more.** Thus, based on the reasoning and the general behavior of height and weight among the given population, we conclude that there is a positive correlation between height and weight.

Bonus Knowledge

B. Positive correlation because taller women tend to weigh more When you analyze the relationship between height and weight, especially in females aged 1 to 21, it's generally observed that as height increases, weight tends to increase as well, particularly during growth stages in childhood and adolescence. This trend is influenced by body composition and muscle development as individuals mature. Therefore, a positive correlation is seen where taller individuals usually have higher weights. Think of it this way: we often associate height with size—like a well-watered garden where taller plants usually have more substantial roots and blossoms. In the same manner, taller individuals often carry more weight, suggesting that these two variables dance together in a positively correlated relationship!
