Last year, the Texas State Penitentiary averaged 14.1 violent incidents per day in its prisons. At the end of last year, the federal courts held that inmates could not supervise other inmates. Warden John Law thinks that this ruling will generate more violent incidents because, in the past, inmates used the supervision hierarchy to maintain a pecking order inside the prison. A sample of 40 days of records reveals a mean of 17.5 and a standard deviation of 2.0. What can you tell Warden Law?
