A researcher studies alcohol's effect on reaction time and finds no difference between people who consumed 3 versus 4 ounces. How might the researcher increase power by exaggerating the differences between groups? Question 8 options: Perform a one-tailed test instead of a two-tailed test. Increase N. Reduce variability by restricting range. Increase the difference between the amounts consumed, such as 3 versus 12 ounces.
