Chapter 1 INTRODUCTION 1.1 Background of the Study Crime is as old as mankind itself. Since the biblical crime back in the days of Cain‚ societies have emerged‚ laws have been created‚ and prohibitions have been declared but violations of forbiddances have continued. Crime has been with us from the very beginning; it has never ceased to disturb men’s living together (Schafer‚ 1996). Crime has negative impacts in many ways. Its costs and effects touch everyone to some degree. The types of costs

the Size of the car being tested. To do this‚ a multiple regression analysis was run using Cost/Mile as the dependent variable‚ and the ‘dummy’ variables Family-Sedan and Upscale-Sedan as independent variables. In examining the results‚ the first thing we notice is the “R Square” value is 0.7471. This represents the multiple coefficient of determination (r2)‚ which is basically a measure of goodness of fit of the equation estimated by the analysis. This means that the size of the car roughly accounts
