Researchers believe that men are more physically aggressive than women.  To test this, researchers ask 20 participants (10 male, 10 female) to rate how aggressive they are on a scale from 1 to 10.  Their scores are listed below. Conduct all six steps of hypothesis testing (use p=.05).  Be sure to label all six steps.  Also, include a concluding statement (which should include the effect size).      Males Females   9 1   8 3   9 5   7 2   8 4   6 3   5 2   9 5   7 4   8 3 M 7.6 3.2 s 1.35 1.32
