You want to know if male or female police officers experience different levels of stress. You collect data from 25 female officers and 30 male officers. (These are independent/non-matched samples.) All members of both groups are given the Police Officer Stress Inventory which has a possible range from 1-10 with higher scores indicating higher levels of stress. Your results are shown below. Group 1: Female Officers Group 2: Male Officers n1=25 n2=30 1=8 2=6 s1=1.5 s2=1.3 Conduct a 2-tailed/non-directional hypothesis test to determine if male or female officers experience different levels of stress. Use an alpha of .01. Be sure to state the null and research hypotheses and interpret your findings in a sentence
