Describe a fictional study in which you would use k-means. Create data using R containing 5 variables and 60 observations that clearly contains 4 groups. Code for generating the data also needs to be included in the code file; but because the data were generated in R, you don't need to save them in a csv file and reload it. Then apply k-means clearly demonstrating that the data contain 4 groups. No need for interpretation of the results
