Question

Please please do this manually

a.What is the distance between the two farthest members? (max or complete link) (round to four decimal places here, and next 2 problems);
b. What is the distance between the two closest members? (min or single link);
c. What is the average distance between all pairs?
d. What is the center distance between two clusters?
e. Among all three distances above, which one is robust to noise? Answer either “complete”, “single”, “average”, and "center"

In Figure 3 there are two clusters A (red) and B (blue), each has four members and plotted in
Figure 3. The coordinates of each member are labeled in the figure. Compute the distance
between two clusters using Euclidean distance.
