Question
The following regression model has been proposed to predict sales at a computer store.
= 50 " 3x1+ 20x2+ 10x3where
x1= competitor's previous day's sales (in $1,000s)
x2= population within 1 mile (in 1,000s)
= sales (in $1000s)Predict sales (in dollars) for a store with the competitor's previous day's sale of $5,000, a population of 20,000 within 1 mile, and nine radio advertisements.
