3 k-Means Clustering We have 8 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 clusters. List those clusters. b) Calculate the centroids of the two clusters c) Reassign obsrvaions to new two clusters.
