Find the Simple Linear Regression Formula of the data set shown below: (10pts)
1 answer:
Uisng technology, such as a linear regression calculator or excel , the linear equation in slope - intercept format which models the data is 171.47x - 125.83
The relationship between <em>advertising cost</em><em> </em><em>and</em><em> </em><em>e-commerce</em><em> </em>sales is positive which can be inferred from the positive value of the slope which models the data. Also, since, the correlation Coefficient is high, we can expect to have a high e-commerce sales whenever, the advertising cost is high.
Therefore, the linear regression equation is 171.47x - 125.83
