The U.S. government provides fuel economy (in milles per gallon) and other information about late model cars sold in the US. A linear regression model was used on the data to determine whether there was an association between a car's engine displacement (Displacement) and fuel economy (MPG). Use the StatCrunch output to answer the following question. Simple linear regression results: Dependent Variable: MPG Independent Variable: Displacement MPG-37.49079-4357743 Displacement Sample size: 35 R (correlation coefficient)--0.79692884 R-sq-0.63509558 Estimate of error standard deviation: 4.0040499 In the dataset, a Volkswagen Beetle has a displacement equal to 2.0 and fuel economy equal to 26. Calculate the residual of this observation and choose the correct answer from the choices below. -40.23 -2.78 2.78 28.78 None of the above
