She collects data on 50 families across the United States, a portion of which is shown in the accompanying table. Click here for the Excel Data File a. Estimate: Consumption = Bo + 81Income + . Compute the predicted consumption expenditures of a family with income of $76,000. Note: Round coefficient estimates to at least 4 decimal places and round final answer to the nearest whole number. Predicted consumption expenditures $ 49,907 b.

Note: Round coefficient estimates to at least 4 decimal places and round final answer to the nearest whole number. Predicted Consumption Urban community 54,255 Rural community 46,924 c. Include a dummy variable Urban and an interaction variable (Income x Urban) to predict consumption for a family with income of $76,000 in urban and rural communities. Note: Round coefficient estimates to at least 4 decimal places and round final answer to the nearest whole number. Predicted Consumption Urban community 76,818 x Rural community 47,022
