Answer:
The correct option is (C).
Step-by-step explanation:
A correlation coefficient is a numerical value that defines the strength of the linear relationship between two quantitative variables.
It ranges from -1 to +1.
In this case the correlation is computed between the gender of workers and their income.
Gender of a worker is not a quantitative variables.
The correlation coefficient r = -0.61 is not defining anything here.
Thus, the correlation coefficient r makes no sense here.
The correct option is (C).
