Suppose an environmental agency would like to investigate the relationship between the engine size of sedans and the miles per gallon (MPG) they get. The accompanying table shows the engine size in cubic liters and rated miles per gallon for a selection of sedans. Use this information to complete parts a through f. Click to view the table showing engine size and MPG for 9 car models. a. Construct a scatter plot for these data. Choose the correct graph below. O A. O B. D D. 32- Engine size MP 19 25 19 MPG Engine Size MPG b. Calculate the slope and y-intercept for the regression equation. The slope is b, = (Round to three decimal places as needed.) X The y-intercept is bo =. Table of Engine Size and MPG (Round to three decimal places as needed.) C. Provide an interpretation for the value of the slope. Car Engine Size Model A 2.5 V. it can be concluded that a one 26 Because the slope is increase in wil the by an average of Model B 2.2 29 (Round to three decimal places as needed.) Model C 2.4 26 d. Predict the MPG for a sedan with a 3.0-liter engine. Model D 3.3 21 Model 3.5 22 The predicted MPG for a sedan with a 3.0-liter engine is | MPG. Model F 21 27 (Round to one decimal place as needed.) Model G 2.2 25 e. Calculate the SST. Model H 21 28 Model I 39 "20 SST =(Round to three decimal places as needed.) f. Partition the SST into the SSR and the SSE SSE = (Round to three decimal places as needed.) Print Done SSR = (Round to three decimal places as needed.)
