G k-Means Clustering We have 10 abservations and would like to do 2-means clustering. Two randomly selected centroids are givin. a) Do the first iteration and devide observations into 2 chusters. List those clusters. b) Calculate the centroids of the two chusters c) Reassign obsrvaions to new two chusters. List those chusters. d) Did you end up with the same two clasters? 2. 3 4 5 Observations 6 Obs. 1 3.00 8.00 7 Obs. 2 4.00 7.00 8 Obs. 3 3.00 6.00 9 Obs. 4 4.00 5.00 10 Obs. 5 5.00 5.00 11 Obs. 6 7.00 5.00 12 Obs. 7 8.00 5.00 13 Obs. 8 3.00 4.00 14 Obs. 9 7.00 3.00 15 Obs. 10 5.00 1.00 16
