Use the advertised prices for a used car of a particular model to create a linear model for the relationship between a car's Year and its Price. a) Find the equation of the regression line. Complete parts a through e. Price ($) Price = + () Year Year 1994 18,467 (Round to the nearest integer as needed.) 1994 18,352 b) Explain the meaning of the slope of the line. Select the correct choice below and fill in the answer box to complete your choice. 1994 18,339 (Round to the nearest integer as needed.) 1994 9,293 1995 20,902 O A. The slope of is meaningless and should not be interpreted. 1995 23,196 1995 22,422 O B. The slope of indicates the Year when the Price of a used car of this model will be $0. 1996 25,512 996 25,676 O C. The slope indicates that for every one Year increase or one Year newer model, the Price decreases by $ 996 24,299 O D. The slope indicates that for every one Year increase or one Year newer model, the Price increases by $ 1997 28,416 1997 27,486 29,821 c) Explain the meaning of the intercept of the line. Select the correct choice below and fill in the answer box to complete your choice. 1997 199 27,808 (Round to the nearest integer as needed. 1997 27,123 O A. The intercept of indicates the Year when the Price of a used car of this model will be $0. O B. The intercept of indicates the Price at Year 0. O C. The intercept of is meaningless and should not be interpreted O D. The intercept indicates that cars of this model increase in price by $ per Year. d) If you want to sell a used car of this particular model from 1997, what price seems appropriate? (Round to the nearest dollar as needed.) e) You have a chance to buy one of two cars. They are about the same age and appear to be in equally good condition. Would you rather buy the one with a positive residual or the one with a negative residual? Explain. You would rather buy the car with a residual because this indicates that the actual price is than the predicted price. This is important because the two cars have the same price, since they are the same age and condition, so the one with the lower price is a better purchase
