Assume that you are investigating causes and effects of crime in the first 51 largest cities in Ethiopia. You have regressed crime rate measured as violent crimes per 100,000 people (crime rate), on other six explanatory variables: murders per 1,000,000 (murder rate), the percent of the population living in slum areas devoid of basic services (slum areas), the percent of the population that is fully employed (employed), percent of population with a high school education or above (educated), percent of population living under poverty line (poverty), and percent of population that are single parents (single). Use the file named 'murder rate data'. What is the purpose of this regression analysis?
1) To determine the factors that contribute to crime rates in the largest cities of Ethiopia
2) To analyze the relationship between crime rates and various socio-economic factors
3) To predict future crime rates in the largest cities of Ethiopia
4) To compare crime rates in the largest cities of Ethiopia with other countries
