Quizplus · Accepted Answer

Using the given data, we can calculate the regression equation in the form of
Y' = b₀ + b₁X₁ + b₂X₂
where Y' is the predicted wage rate, X₁ is the performance rating and X₂ is the number of economics courses completed. 
By running the regression analysis, we get the following results:
b₀ = 6.932
b₁ = 0.616
b₂ = 1.054
Therefore, the value for the regression constant, b₀ is 6.932.
