The higher the correlation between X and Y, then
A) the higher the probability of having isolated the causal factor
B) the higher the probability of having sampled from a single population
C) the higher the probability of inflating the alpha error
D) the more accurate the resulting predictions

A high correlation between X and Y indicates that there is a strong relationship between the two variables. This strong relationship can make predictions more accurate, as changes in one variable are likely to be mirrored in changes to the other. However, it does not necessarily indicate causation, and the alpha error (the probability of incorrectly rejecting the null hypothesis) is not impacted by the correlation. Therefore, the best choice is D, as it represents the positive aspect of a high correlation.
