Suppose we are interested in estimating the differences between mean crime rates in southern states and non-southern states. we will use expend1960 and malesperfemales as potential covariates. for parts a. through d. below, estimate the given model, and enter estimated coefficients for each predictor, along with their corresponding p-values, and the r2 statistic for the model. note that p-values for the intercepts are not requested because the intercept is not of scientific interest. for all numeric questions, round your answers to three decimal places.
a. crimeratei = β0 + β1southerni + εi
b0=
b1= p-value=
r2=
b. crimeratei = β0 + β1southerni + β2malesperfemales + εi
b0=
b1= p-value=
b2= p-value=
r2=
c. crimeratei = β0 + β1southerni + β2expend1960 + εi
b0=
b1= p-value=
b2= p-value=
r2=
d. crimeratei = β0 + β1southerni + β2expend1960 + β3malesperfemalesi + εi
b0=
b1= p-value=
b2= p-value=
b3= p-value=
r2=
