use the scatter plot to answer the question. which value is the best estimate for the correlation coefficient of the data set? a. 1 b. 0 c. -0.2 d. -0.5 e. -0.8

Answer

Explanation:

Step1: Analyze scatter - plot trend

The points in the scatter - plot show a negative trend, meaning as x increases, y generally decreases. So the correlation coefficient r is negative.

Step2: Evaluate strength of correlation

The points are not tightly clustered around a line, so it's not a strong negative correlation (r close to - 1). It's also not a very weak negative correlation (r close to 0). A value of r = - 0.5 seems to be a reasonable estimate as it indicates a moderate negative linear relationship.

Answer:

D. -0.5
