A microcomputer manufacturer has developed a regression model (n=35) relating his sales (y in $10,000s) with three independent variables. The three independent variables are price per unit (Price in $100s), advertising (ADV in $1,000s) and the number of product lines (Lines). The sample size n=90. Part of the regression results is shown below.
