Some citizens complained to city council members that there should be equal protection under the law against the occurrence of crimes.

Suggest a reallocation of crime protection effort, if indicated, based on a p-chart analysis. To be reasonably certain in your recommendation, select a 95 percent confidence level (that is, Z =1.96).
