ProblemB: City Crime and Safety

What can we makeof the massive amount of crime statistics collected in major cities? Beyondjust reporting numbers, how can we use these data to determine the safeness ofa city?

Assume that youand your modeling team live in My City, a large international hub of commerce,technology, finance and travel, with a current population of 2.8 million peopleimpacted by a metropolitan area of an additional approximately 6 millionpeople.

The data setprovided (My_City_Crime_Data.xlsx   ) shows two weeksfrom police reports in My City and includes crimes listed by case number, dateof occurrence, primary and secondary crime descriptions, crime location,whether an arrest was made, whether or not this was domestic crime, and thebeat number of the police route.

Part I:Using mathematical modeling, analyze the data. Create a safetyrating for My City. Use your safety rating to specify a measure of how safe MyCity is.

Part II: In addition to the HiMCM contest format, prepare a 1-2 pagenon-technical report for the Mayor of My City to describe your findings.
