British biologist Ronald Fisher studied iris flowers and classified them according to the width and length of the flower’s petals and sepals (a small, green leafy part below the petal). The accompanying table shows a portion of the data that Fisher used in his study. 

a. Perform k-means clustering using k = 4. What are the size and cluster center values of the largest cluster? 

b. Experiment with k = 3 and k = 5. What are the size and cluster center values of the largest cluster in each case?
