Regression Analysis

The cost of a previously owned car depends upon factors such as make and model, model year, mileage, condition, and whether the car is purchased from a dealer or from a private seller. To investigate the relationship between the car's mileage and the sales price, data were collected on the mileage and the sales price for ten private sales of model year 2000 Honda Accords as summarized below. We want to use the least squares method to develop an estimated regression equation. Data is in Table 1 (see attached picture)
