If the correlation between variables A and B is zero,what can we conclude?
A)A and B have the same mean, the same median, and the same distribution.
B)As A goes up, B does not consistently go either up or down.
C)The mean value of either A or B must be zero.
D)If we know the value of A, we can predict the value of B with zero error.

If the correlation between variables A and B is zero, it means that there is no linear relationship between them. As A goes up, B does not consistently go either up or down. However, the other choices are not necessarily true. A and B can have different means, medians, and distributions, and the mean value of either A or B does not have to be zero. Additionally, if we know the value of A, we cannot predict the value of B with zero error, as there could still be variability or randomness in their relationship.
