Answer:
Option C is correct.
The value of r=0.2 represents the weakest correlation.
Step-by-step explanation:
Strongest correlation states that a linear relationship is indicated by a correlation coefficient of -1 or 1.
Weakest correlation states that a linear relationship is indicated by a correlation coefficient equal to 0 or if the value is nearest to 0, then it also represents the weakest correlation.
From the options, the only r-value that is very close to 0 is 0.2.
Therefore, the r-value represents the weakest correlation is, 0.2
