** The Following implemented in R (R Studio) **

1. Set up the Auto data:
   1. Load the ISLR package and the Auto data
   2. Determine the median value for mpg
   3. Use the median to create a new column in the data set named mpglevel, which is 1 if mpg>median and otherwise is 0. Make sure this variable is a factor. We will use mpglevel as the target (response) variable for the algorithms.
   4. Use the names() function to verify that your new column is in Auto
   5. create a 75-25 train/test split, using seed 1234 but do not include columns name or mpg in either train or test
