Linear regression analysis

• Consider the auto dataset below.

I want to build a simple linear regression predicting mpg as a y variable (SAS code, please).

(a) Make scatterplots of mpg vs other variables (put all plots in one page). Based on these plots, choose one numerical variable that you think may be used effectively to predict mpg. (b) Fit a simple linear regression model and carry out regression diagnostics. The analysis should include an assessment of the degree to which the key regression assumptions are satisfied. Clearly state each assumption, the diagnostic tools used to check it, and the conclusion. (c) If an assumption is not met, attempt to remedy the situation. Explain the steps used to obtain the final model. Comment on the fit the final model using appropriate tests and statistics
