You wish to see whether guards in your prison have significantly higher levels of ethical violations compared to similar sized correctional facilities. You randomly sample 315 guards at your prison and find that they averaged 2.4 ethical violations per guard, with a standard deviation of 1.0. The average for all correctional guards across the state is 1.5 violations. Assume an alpha of .01 for this problem. a. State the appropriate null and research hypothesis, as suggested in the problem above. b. Use the one-sample (large sample) hypothesis test to calculate Z(obtained). c. Pretend you got a Z(obtained) of +1.58 (ignore whatever you got in B above), with a Z(critical) of +2.58. How would you interpret the results?
