In the context of parametric tests, what should one do when the two means being compared come from samples that are not independent of one another? Multiple choice question. One should compute an error term based on the standard error of the mean provided separately by each sample. One should compute an error term based on the two samples combined, assuming that both samples come from populations having the same mean. One must compute an error term based on the two samples combined, assuming that both samples come from populations having the same variance. One must adjust the formula for the t test to take into account any correlation between scores
