The owner of Maumee Ford Volvo wants to study the relationship between the age of a car and its selling price. Listed below is a random sample of 12 used cars sold at the dealership during the last year. Age Selling Price (5000) (years) 8.1 Car 1 2 3 4 5. 6 7 B 9 10 11 12 7 11 12 B 7 8 11 3.6 4.0 5.0 10.6 7.6 8.0 8. 6.0 8.6 8.0 12 6 6 a. If we want to estimate selling price on the basis of the age of the car, which variable is the dependent vanable and which is the independent variable? Answer is complete and correct. is the independent variable and selling price is the dependent variable Age b-1. Determine the correlation coefficient. (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.) - 2 y-y (31 - ?)
