1. Using the denrogram below, draw a horizontal line which will divide the underlining observations into 11 clusters.
a) List all observations in each cluster (or highlight each cluster).
b) What is the (approximately) maximum dissimilarity within each of 11 cluster?
c) Based on this dendrogram, i) what would be the good number of clusters to use?; ii) what are those clusters;? Iii) What is the maximum distance within those clusters?
