what is the best estimate for the correlation coefficient of the data shown in the scatter plot?\na. 0.89\nb. 0.12\nc. -0.12\nd. -0.89

Answer

Explanation:

Step1: Observe the scatter - plot trend

The points in the scatter - plot show a general downward trend. This indicates a negative correlation.

Step2: Assess the strength of the correlation

The points are somewhat scattered but still show a noticeable linear trend. A strong negative correlation has a correlation coefficient close to - 1, and a weak negative correlation has a coefficient close to 0. Since the points are not extremely tightly clustered around a line but still have a clear downward trend, the correlation coefficient should be moderately negative.

Answer:

D. - 0.89
