Using 2-mean clustering method, suppose you cluster 6 consumers based on two features (x1, x2). In cluster A you put 3 consumers with values (2,6),(3,4), and (3,5); and in cluster B you put the remaining 3 consumers with values (4,5), (5,4), and (6,3). Using Euclidean distance, which of the following is the total sum of squares of the 2-means cluster?
