The motorboat from #8 is newer and built with aerodynamic and lightweight material. The residual for max speed is 5.48 mph. What is the actual max speed for this motorboat? Type a response Use the information from questions #8 & 9 to explain the residual. Did the linear model (equation) overpredict or underpredict the max speed of the motorboat? Type a response Use the HP vs Max Speed of Motorboats. Now check the residual plot for the HP vs Max Speed to determine if it is appropriate to continue using the Linear Model to make predictions. 1. What do you see? 2. What does this mean? Random scatter on the residual plot. A curved pattern reading from left to right. A positive linear relationship reading from left to right. The calculated linear model may not be appropriate for making predictions. The calculatoed linear model is appropriate for making predictions. Horsepower 60 80 90 115 150 250 300 Boat Motor Speeds A. B. Top Speed (mph) 25 Now that the data is in L1 & L2 of your calculator. Do a linear regression to create the Linear Model: Stat, Calc, #8LinReg. Select the correct linear model from the list below: 20 40 45 50 55 60 HP = 21.12 +0.14(MPH) HP = 0.14 +21.12(MPH) C. MPH = 0.14 + 21.12(HP) D. MPH = 21.12 + 0.14(HP) E.
