97 5.0 2.5
90 2.0 2.0
96 5.0 2.5
93 3.5 2.5
95 3.0 4.3
95 4.5 2.3
94 2.5 5.2
94 3.0 2.5

The estimated regression equation was:_______

Answer 1

Answer:

ŷ = 1.85057X1 + 0.9688X2 + 84.77516

Step-by-step explanation:

Given the data:

Newspaper Advertising (X2) :

2.5

5.2

2.5

The regression equation obtained using a multiple regression calculator is :

ŷ = 1.85057X1 + 0.9688X2 + 84.77516

x1 and x2 are the predictor variables

y is the predicted variable (Weekly Gross Revenue).

Slope x1 = 1.85057

Slope x2 = 0.9688

Intercept = 84.77516
