Sociology/Criminology/Economics: Records comparing unemployment rates and property crime rates (per 1,000) were gathered in a state for the years 1975 - 2005 (n = 31). Below is the scatterplot, regression line, and corresponding statistics for these 31 years. Property Crime Rate -vs- Unemployment Rate Property Crime -vs- Unemployment x = Unemployment Rate (in %) y = Property Crime Rate (in crimes per 1,000 people) Property Crime Rate (per 1000) correlation coefficient: r = 0.825 59.0 54.0 49.0 44.0 39.0 34.0 29.0 24.0 regression equation: ý = 3,0x + 26.0 8 10 12 sample size: n = 31 Unemployment Rate (%) Answer the following questions regarding this relationship. (a) What is the y-intercept of the regression equation? O 3.0 31 O 0.825 0 26.0 (b) With respect to the variables involved, choose the best interpretation of the y-intercept. Provided the relationship remains linear, you can expect an unemployment rate of 26.0% if the property crime rate is 0. It represents the minimum crime rate of the 31 years depicted in the scatterplot. Provided the relationship remains linear, you can expect a property crime rate of 26.0 (per 1,000 people) if the unemployment rate is 0%. It represents the maximum expected crime rate, regardless of the unemployment rate.
