1. 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.
2. Please submit your solution (step-by-step calculations ), and the conclusion, at the 95% level of confidence, here. The data and hypotheses are as follows:

% of College educated officers who had an abuse complaint filed against them in the previous 12 months

15

N=485

% of Non-college educated officers who had an abuse complaint filed against them in the previous 12 months

18

N=612

Ha: College-educated officers will havefewerabuse complaints filed against them

Ho: Their levels of education do not affect the proportion of abuse complaints filed against police officers
