95	3.0	3.3
94	3.5	2.3
94	2.5	4.2
94	3.0	2.5

a) Develop an estimated regression equation with the amount of television advertising as the independent variable. (Round your numerical values to two decimal places. Let x₁ represent the amount of television advertising in $1,000s and y represent the weekly gross revenue in $1,000s.) Y=????

B) Develop an estimated regression equation with both television advertising and newspaper advertising as the independent variables. (Round your numerical values to two decimal places.

Y=????

C) Predict weekly gross revenue (in dollars) for a week when $3,100 is spent on television advertising and $1,100 is spent on newspaper advertising. (Round your answer to the nearest cent.)
