The output of a different regression analysis on the effect of radio advertising spending, television advertising spending and online advertising spending on sales is given below. For this study they explored 3 different types of advertising spending (radio, television and online). They modelled it as y = ao + a1¤1 + azT2 + azT3 . The table below gives the output of this regression analysis.
