Use the results from the example presented in Computational
Example 11.2 and similar results obtained by you for k = 5 and k = 6 to
produce a plot.

Examine the output for K-means, k = 3 in Computational Example
11.2. Suppose that you wanted to perform a classification of a set of
unknown vectors based upon their similarity to the average pattern typical of
Cluster 2.
a. What pattern vector could you use to represent Cluster 2?
b. For classification, you would need to produce a score that reports how close
any candidate vector is to the pattern vector. What function discussed in
Section 11.5 could be used to produce this score?
c. Compute scores for previously defined members of Cluster 2 relative to
the pattern vector representing Cluster 2 as a whole.
d. Score previously defined members of Cluster 1 to test how well they conform
to the pattern of Cluster 2.
