1) A sociologist is curious if the poverty level of children in large cities can be predicted with a linear model based on the city's crime rate. Load the data into Stata using the command use http://people. fas.harvard.edu/~mparzen/stat104/poverty.dta a) Using Poverty as the "Y" variable and Crime as the "X" variable, create a scatter plot. Does there appear to be a linear relationship? b) What is the value of R-sq? Would you say it is a high or low value? c) Test the hypothesis HB =0H B0. Fully explain your conclusion. a d) Should we use this regression equation to predict children's poverty levels from the crime rates? Explain.
