The following regreion model ha been propoed to predict ale at a computer tore:
y_hat = 50 – 3x1 20x2 10x3
where
x1 = competitor' previou day' ale (in $1000)
x2 = population within 1 mile (in 1000)
x3 = 1 if any radio advertiing wa ued and 0 otherwie. Y_hat= ale (in $1000)
Predict ale (in dollar) for a tore with the competitor' previou day' ale of $5000, a population of 20,000 within 1 mile, and nine radio advertiement
