Z = (score-mean)/SD
Need mean and standard deviation for ALL CITIES to find Z scores.
According to 2010 UCR data, Oakland, CA has a murder rate of 22.0 (per 100,000) in 6th place, Washington, DC has a murder rate of 21.9 in 7th place, and Kansas City, MO has a murder rate of 21.1 in 8th place. If we looked at all U.S. cities with a population of 250,000 and converted their murder rates into z-scores in what order would Oakland, Washington, and Kansas City fall after the conversion? Explain your reason for this.
