Answer:

Based on the scatterplot provided, we can observe that the data points form a linear relationship with a negative slope. The correlation coefficient measures the strength and direction of this relationship.

Looking at the given options:

A) -0.98: This value indicates a strong negative correlation, which aligns with the scatterplot showing a downward trend.

B) -1.43: Correlation coefficients range from -1 to 1, so -1.43 is not a valid value.

C) 0.99: This value represents a strong positive correlation, which contradicts the scatterplot showing a negative trend.

D) 0.34: This value represents a weak positive correlation, which contradicts the scatterplot showing a negative trend.

Therefore, the best option that represents the relationship in the scatterplot is option A) -0.98, indicating a strong negative correlation.
