A professor at the University of Wisconsin is interested in studying the relationship between officer’s gender and citizen complaints. The professor gathered information on 55 officers randomly sampled from the Chicago Police Department. Using the data collected below apply the five steps of the hypothesis testing process to answer the research question: is there a relationship between gender and citizen complaints. Use a two-tailed test with an alpha level of 0.05 Male Officers Female Officer n = 35 n = 20 M = 10.57 M = 8.34 SS = 901.34 SS = 794.34 Step 4. Make a decision about the null and research hypothesis. Compute and interpret Cohen’s d effect size. Compute the 95% confidence interval for mean difference
