The U.S. government provides fuel economy (in miles 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-37.49079-4.357743 Displacement Sample size: 35 R (correlation coefficient) = -0.79692884 R-sq-0.63509558 Estimate of error standard deviation: 4.0040499 Identify the slope, intercept, and association (positive or negative) and choose the correct statement below. The slope is 37.49, the intercept is -4.36, and the association is negative. The slope is 37.49, the intercept is -4.36, and the association is positive. The slope is -4.36, the intercept is 37.49, and the association is negative. The slope is -4.36, the intercept is 37.49, and the association is positive.
