Perform agglomerative clustering on the accompanying data set. Use the first five variables, x1, x2, x3, x4, and x5, in the analysis. Do not standardize the variables. a. Use Jaccard's coefficients for the similarity measure and average linkage for the clustering method to cluster the data into four clusters. How many 1s are in x1 of the largest cluster? Number of 1s in the largest cluster b. Use Jaccard's coefficients for the similarity measure and single linkage for the clustering method to cluster the data into six clusters. How many 1s are in x1 of the largest cluster? Number of 1s in the largest cluster 10 A C E F H.
