You wish to assess whether Los Angeles has an equitable distribution of police services among its precincts compared to nearby cities.  You theorize that if police resources are distributed equitably, average response times for emergency calls should be fairly similar from one precinct to another within the city.  On the other hand, if response times are much higher in some precincts than others, police resources are probably not distributed as equitably as possible.  You decide to compare the City of LA to the other cities in the rest of LA County.  You are hypothesizing about differences in the mean between the City of LA and other cities.  State in plain English the null and research hypotheses for this study.
