Develop a simple linear regression model to predict a vehicle's highway fuel efficiency (Hwy FE - Conventional Fuel) based upon number of cylinders (# Cylinders) using a 95% level of confidence. a. Write the regression equation b. Discuss the statistical significance of the model as a whole using the appropriate regression statistic at a 95% level of confidence. c. Discuss the statistical significance of the coefficient for the independent variable using the appropriate regression statistic at a 95% level of confidence. d. Interpret the coefficient for the independent variable. e. What percentage of the observed variation in highway fuel efficiency that is explained by the model? f. Predict a vehicle's highway fuel efficiency that has 6 cylinders using your equation from part a.
