question 23 of 25
which graph has a correlation coefficient r closest to -0.99?
a. graph a
b. graph b
c. graph c
d. graph d

Explanation:

Step1: Recall the property of negative correlation

A negative correlation coefficient means that as one variable increases, the other variable tends to decrease. So, the scatter - plot should show a downward trend.

Step2: Analyze each graph

• Graph A: No clear trend (either positive or negative).
• Graph B: Shows a downward trend (as \(x\) increases, \(y\) decreases).
• Graph C: Shows an upward trend (positive correlation).
• Graph D: No clear trend (either positive or negative).

Answer:

B. Graph B
