A federal government agency that is responsible for setting vehicle fuel economy standards for automobile manufacturers is conducting research in order to update its fuel economy standards for the year 2030. Automobile manufacturers, and consumers, are highly interested in what the agency's findings and determinations will be as this will affect every vehicle in the United States. The federal government agency is very interested in the relationship between the weight of a vehicle and the vehicle's fuel economy (average miles per gallon (MPG)). Specifically, the agency is concerned that if the current trend of automobile manufacturers producing heavier new vehicles continues that its fuel economy targets will not be met. The agency's research department recently collected data for analysis in order to support the agency's upcoming discussion with industry regarding its proposed 2030 fuel economy standards. The average MPG from a random sample of 750 vehicles was recently calculated by the agency. The research division also collected the vehicle weight of these 750 randomly sampled vehicles. The Vehicle Number, Type, Vehicle Weight, Average MPG, Fuel Tank Size (Gallons), Engine Size (Liters), and Meet or Not Meet Current Standards data were collected for these 750 vehicles.Agency leadership wants to create a simple linear regression model to predict a vehicle's average fuel economy based upon the weight of the vehicle. Create a scatterplot using Vehicle Weight as the independent variable and Average MFG as the dependent variable. Perform a visual analysis of the data: describe the trend, strength and shape at the relationship between these two variables. Choose the correct answer below. 0 A. The scatterplot indicates there is a negative, weak, linear relationship between Vehicle Weight and Average MPG. O B- The smtterplot indicates there is a positive, weak, linear relationship between Vehicle Weight and Average MPG. O C- The scatterplot indicates there is a positive, strong, linear relationship between Vehicle Weight and Average MPG. O D- The smtterplot indicates there is a negative, strong, linear relationship between Vehicle Weight and Average MPG. O E- The smtterplot indicates there is no relationship between Vehicle Weight and Average MFG. Include the scatterplot image as part of your answer. Save the image as a .jpg or .png file, then click "Show Work" and use the "Insert Image" button to upload and save your scatterplot. Based upon your visual analysis of the scatterplot, is simple linear regression appropriate? Why or why not? BIUST E Insert Formula
