Null hypotheses typically state that there is no relationship between variables (option A) and are used to determine how likely it is that observed results are due to chance alone (option B). However, researchers do not typically hope to retain null hypotheses (option C) as they are usually attempting to find a significant relationship between variables. Therefore, options A and B are true, but option C is not.
