Question 1: 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. StatCrunch Data Setopens in a new tab Question content area bottom Part 1 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 MPG as the dependent variable. Perform a visual analysis of the​ data: describe the​ trend, strength and shape of the relationship between these two variables. Choose the correct answer below. A. The scatterplot indicates there is a​ positive, strong, linear relationship between Vehicle Weight and Average MPG. B. The scatterplot indicates there is a​ negative, weak, linear relationship between Vehicle Weight and Average MPG. C. The scatterplot indicates there is a​ positive, weak, linear relationship between Vehicle Weight and Average MPG. D. The scatterplot indicates there is a​ negative, strong, linear relationship between Vehicle Weight and Average MPG. E. The scatterplot indicates there is no relationship between Vehicle Weight and Average MPG. Include the scatterplot image as part of your answer.

​(Round to two decimal places as​ needed.)
Part 2
Interpret the correlation coefficient is this context.
There is strong negative correlation between Vehicle weight and Average MPG. It means as the weight of vehicle increases the average MPG goes on decreasing.
