(a) Develop an estimated regression equation that predicts the selling price of a used Honda Accord given the mileage and age of the car. (Round your numerical values to two decimal places. Let x₁ represent mileage, x₂ represent age, and y represent the selling price.)
y=20087.1 -0.04x₁ - 642.15x2
(b) Is multicollinearity an issue for this model? Find the correlation between the independent variables to answer this question. (Round your answer to two decimal places.)
The correlation between age and mileage is
Since this is <✔✔✔ 0.70, we conclude that multicollinearity is not
an issue.
