Consider the data points in Table F3: P1 58 68 P2 143 104 P3 135 131 P4 176 81 P5 132 113 P6 86 32 P7 182 9 P8 167 31 Table F3 a) Do hierarchical clustering by single linkage method. Make the dendrogram also. b) Perform K-means clustering with k=3 and initial starting values as: Centroid I (58, 68) Centroid 2 (132, 113) and Centroid 3 (167, 31). Plot the final clusters also with the help of the scatter chart.
