Researchers call position (a) null hypothesis (symbolized H0). Researchers call position (b) alternative hypothesis (symbolized Ha). A researcher customizes the hypotheses to a study, using symbols and information about the specific study.
Indicate your research hypotheses (null and alternative), incorporating the appropriate symbols. [To answer this question, you need, in part, to look at the research scenario.]
State what the hypotheses mean. [Some overlap may exist with your answer to # 1. These are related rather than mutually exclusive questions.]
