The Department of Energy website contains data on 1209 model year 2016 cars and SUVs.10 Included in the data are the engine size (as measured by engine displacement in liters) and combined city and highway gas mileage (in miles per gallon). When you make a scatterplot to predict gas mileage from engine size, the explanatory variable on the x axis
1. is the gas mileage.
2. is the engine size.
3. can be either gas mileage or engine size.
Homework Answers
We want to predict gas mileage from the engine size
Hence here the x variable that is the explanatory variable is engine size.
While making scatterplot the explanatory variable on tha x axis is the engine size.
Becouse in scatterplot explanatory variable is always on x axis.

Question 22 3 pts A regression analysis was done on 81 different SUV vehicles. The variables analyzed Included are the average gas mileage in miles per gallon (Average MPG) and the engine size in liters (Engine Size). The average miles per gallon is a weighted average of city and highway driving to reflect a 40/60 percent split. The estimated regression equation is: Average MPG = 27.654 - 2.114*Engine Size R-squared = .4615 Based on the regression model, the estimated value...

In its Fuel Economy Guide for 2014 model vehicles, the Environmental Protection Agency gives data on 1160 vehicles. There are a number of high outliers, mainly hybrid gas-electric vehicles. If we ignore the vehicles identified as outliers, however, the combined city and highway gas mileage of the other 1134 vehicles is approximately Normal with mean 22.2 miles per gallon (mpg) and standard deviation 5.2 mpg. 2014 Volkswagen Beetle with a five-cylinder 2.5L engine and automatic transmission has combined gas mileage...
