1.The national track records data for women are given in Table 1.9 (Book: applied multivariate statistical analysis, author: Richard A. Johnson) (a) Using the data in Table 1.9, calculate the Euclidean distances between pairs of countries. (b) Treating the distances in (a) as measures of (dis)similarity, cluster the countries using the single linkage and complete linkage hierarchical procedures. Construct dendrograms and compare the results. (c) Input the data in Table 1.9 into a K-means clustering program. Cluster the countries into groups using several values of K. Compare the results with those in Part b
