Refer to Table 9.1 and the Crime2 data file at the text website. For all 51 observations, use software to analyze the relationship between y = murder rate and x =

poverty rate.

(a) Construct a scatterplot. Does there seem to be a positive, or a negative, relationship?

(b) Report the prediction equation, and find the predicted murder rate and the residual for D.C. Interpret.

(c) Based on the scatterplot, would you regard D.C. as a regression outlier? Refit the model without it, and note the effect on the slope.
