PART V: Hypothesis Testing You are interested if men and women correctional officers differ in salary amounts based on whether or not they have witnessed a physical altercation in prison. You survey correctional officers from three different prisons across the state. You hypothesize that men who witnessed a physical altercation will have a lower salary than women who witness a physical altercation. Below are the data that tests this hypothesis.

(That is, are we assuming equal variances?) Explain your answer or you will not get credit. (2 points)
