points) Table 2 shows a data set with four data observations, i.e. (x,y), i = 1,2,3,4. Table 2: Data set for problem 4 1234 X 245 (1) If randomly assign observations 1, 2 and 3 to cluster I and observation 4 to cluster 2, show your calculations to implement K-meas clustering, What will be the final clustering results? (7 points) (2) For the same data set in Table 2) show your calculations to implement the agglomerative hier- archical clustering with single linkage and draw the corresponding dendrogram. (6 points) (3) Based on the dendrogram drawn in part (2), what will be the clustering results if we need two clusters? (2 points)
