It is thought that one tangible benefit of increasing the educational requirements for incoming police officers would be a decrease in the number of police brutality complaints filed by citizens each year. To test this idea, we can use Z to test two independent samples of police officers -- one group with college degrees, the other without. A random sample of officers was selected from one state.

Please submit your solution (step-by-step calculations ), and the conclusion, at the 95% level of confidence, to the Lesson 9 z Scores drop box. The data and hypotheses are as follows:

% of College educated officers who had an abuse complaint filed against them in the previous 12 months	% of Non-college educated officers who had an abuse complaint filed against them in the previous 12 months
15	18
N=485	N=612

H_a: College-educated officers will have fewer abuse complaints filed against them
