Which of the following correlation coefficients is plausible for a study that showed that the weight of people's clothing increases as the temperature decreases?
A)r = +.20
B)r = 0.00
C)r = -.20
D)r = -2.0

A negative correlation coefficient (option A) is plausible as the data suggests that as one variable (temperature) decreases, the other variable (weight of clothing) increases. However, the correlation coefficient cannot be less than -1. Therefore, option D (-2.0) is not a plausible choice.

Option B (0.00) suggests no relationship between the two variables, which is not supported by the study. Therefore, option C (-.20) is the best choice among the given options.
