Math Problem Statement
Solution
From the uploaded image, the question is asking to identify which scatter plot shows a negative linear association. Here's an analysis of the scatter plots:
- Negative Linear Association means that as the values of one variable increase, the values of the other variable decrease, forming a downward slope.
Observations:
- Bob's scatter plot: This appears to have a U-shape, which does not represent a consistent linear association.
- Peter's scatter plot: Displays a positive linear association (as one variable increases, the other also increases).
- Janet's scatter plot: The points are scattered without any discernible linear pattern, so there's no association.
- Macy's scatter plot: This shows a negative linear association (a clear downward trend).
Correct Answer:
The correct answer is Macy.
