Tab 2 2b---Will control for Newspaper while explaining the Radio coefficient and vice versa for Newspaper coefficient. I agree \$1,000 is the unit of increase for each form of advertising; however, I disagree predicted sales is only \$13.08 and \$16.80 respectively. Sales are in thousands of dollars as is the levels of media expenditure. The dollar amount for sales will respond accordingly to advertising expenditure. Your response should include a ?\$? symbol where applicable. 2c---b0 is the intercept coefficient, but what does the intercept coefficient mean? Can we conclude that if the x variables are set equal to zero, we can expect this level of sales (in thousands) or is the data outside the historical values and the intercept simply anchors the regression line?
