A researcher asks the question "Is there a relationship between GRE total scores and GPAs in the master's programs in electrical engineering?" The researcher's null hypothesis states, "There is no correlation between GRE total score and GPA from an electrical engineering master's program." The researcher's alternative hypothesis states, "There is a positive correlation between GRE total scores and GPA from an electrical engineering master's program."
Are these valid hypotheses for the research question? Why or why not? What other observations can you make regarding the hypotheses and research question?
