Now, use stratified sampling to split the Sacramento dataset (used above) into a train and test sample with 80% of the data going to the train sample. Do the sampling in such a way that the distribution of price is approximately equal in both samples. Use a seed of 1706 and utilize createDataPartition from caret package, for the split and set groups to 50. What is the absolute difference in average price between the train and test samples? This question uses R or RStudio with the following packages: install.packages(ISLR') install.packages('caret') install.packages('caTools') Do not round answers from R. Enter them as is.
