This output tells us the regression line equation is: margin=-5.2 +8.4home. What was the Nets' average margin of victory for games in 2014 when they were the away tea (i.e. when home=0)? (round to 2 decimal places)

Question
![Consider data on every game played by the Brooklyn Nets in 2014 (82 games) that includes the
variables
margin; - the Net's margin of victory (number of points the Nets scored minus the number of
points their opponent scored) for game i, and
• home; - a dummy variable equal to 1 when the Nets are the home team (game i was played in
their home arena) and equal to 0 when they are the away team (game i was played in the
opponent's arena).
I use the least-squares method to estimate the following regression model
margin = a + ßhome; + ei
Below is the Stata output corresponding to the estimated regression line:
regress margin home if team==== "Brooklyn Nets"
