A study finds that 25% of the variance in IQ can be explained by the variance in working-memory capacity. In other words, an R2 of .25 was observed between the two variables. Null-hypothesis significant testing confirmed that this R2 value was significantly different than zero. Based on this information alone, what can you say about what the study found? Group of answer choices a non-significant correlation was observed between IQ and working-memory capacity A significant correlation was observed between IQ and working-memory capacity That a Pearson's r correlation coefficient of .50 was observed between IQ and working-memory capacity
