A. A set of nine data pairs with a correlation coefficient r = -0.4
Step-by-step explanation:

When performing regression analysis it is generally accepted by researchers that each variable should have at least 10 observations.
Therefore, the data set having nine data pairs with a negative correlation of -0.4 will provide the most valid result that can then be used for generalization about the larger statistical population.
