n this problem, you will practice PCA on the BOST ON dataset from the library M ASS. (a) First, scan through the dataset and remove the categorical variable(s) from the dataset, because PCA only works for numerical variables. (b) Remove the variable medv so you can perform PCA on the rest of the variables. (c) Use prcomp() function in R to perform PCA. Make sure that you set scale = T RU E, so R will do the data scaling for you automatically. Report the standard deviation of each principle component. 3
