Develop an estimated regression equation with the amount of television advertising as the independent variable (to 1 decimal). Revenue = |TVAdv b. Develop an estimated regression equation with both television advertising and newspaper advertising as the independent variables (to 2 decimals). Revenue = TVAdv + NVAdv c. Is the estimated regression equation coefficient for television advertising expenditures the same in part (a) and in part (b)? - Select your answer - Interpret the coefficient in each case. In - Select your answer - :, the coefficient is an estimate of the change in revenue due to a one-unit change in television advertising expenditures. In - Select your answer - :, the coefficient is an estimate of the change in revenue due to a one-unit change in television advertising expenditures with the amount of newspaper advertising held constant. d. Predict weekly gross revenue for a week when $3,500 is spent on television advertising and $2,000 is spent on newspaper advertising?
