For the sales regression in the very previous question, What is the numerical value of b0, or the sample intercept coefficient for the sales regression? The data is reproduced above for your convenience. Also, here is the sample regression function that you should get values for…. Yi = b0 + b1Xi + ei where Yi = sales (in millions) and Xi = advertising expenditures (in millions)
