What are the correct interpretations of the estimated regression parameters? Are these interpretations reasonable?
(i) Bo is the estimate of change in the weekly gross revenue if newspaper advertising is held constant and there is a $100 increase in television advertising. B1 is the estimate of change in the weekly gross revenue if television advertising is held constant and there is a $100 increase in newspaper advertising. B2 is the estimate of the weekly gross revenue when television and newspaper advertising are both
zero. The interpretation of Bo, B1, and B2 are all reasonable.
(ii) Bo is the estimate of the weekly gross revenue when television and newspaper advertising are both zero. B1 is the estimate of change in the weekly gross revenue if newspaper advertising is held constant and there is a $100 increase in television advertising.
