A) In the distance matrix there is a missing distance x. Compute its value and write it. B) Consider two arbitrary clusters AD and BCEFG. Compute and write the dissimilarity between these clusters under "average" linkage. C) Using the above data X, the R command KM<-kmeans (x=X, centers=3) was run, with the following output > KM$cluster [1] 3, 2, 3, 3, 2, 1, 1 There is interest in determining the center of the cluster identified with the label 2. By computing this center manually or otherwise, identify which of the following is the correct centroid of this cluster: D) Still using the above data X, the R command pam (x=X, k=3)->PM was run, with the following output: > PM$id.med [1] 1, 2, 6 Identify correctly the medoids yielded by this cluster analysis.
