The first 15 cars (year, mileage, and price) were selected such that no more than 2 cars are from a year. You can subtract the model year from 2017 to obtain age. Add "trend line" through the data in Excel to show the fit for the following regression models: a. Linear models between price as a function of age and mileage as shown by Equations (1) and (2): Price age = a + b x Age (1 ) Price age = a + bx Mileage (2) b. Power models between price as a function of age and mileage as shown by Equations (3) and (4): Price age = ax Age (3) Price age = ax Mileage (4 ) 1 of 2
