Consider the following clustering problem that has a single variable X. What is the complete linkage dissimilarity measure (based on the usual Euclidean distance) between the two clusters {1, 4.2, 5.3} and {7.1, 9}? (Hints: The cluster {1, 4.2, 5.3} corresponds to three observations of X grouped together where X=1 for the first observation, X=4.2 for the second and X=5.3 for the third. Similarly, the cluster {7.1, 9} corresponds to two observations of X grouped together. Finally, the Euclidean distance between two different points x1 and x2 is obviously here the absolute value of the difference, in other words |x1-x2| )
Question 3 Using the region names in the image below, select all regions that represent: A ∩ B' ∩ C A intersection not B intersection C. Region I: Items only in group A, not in B or C. Region II: Items in A and B, but not C. Region III: Items only in B, not in A or C. Region IV: Items in A and C, but not B. Region V: Items in A, B, and C. Region VI: Items in B and C, but not A. Region VII: Items only in C, not in A or B. Region VIII: Items not in any of the groups.
In the Focus Problem at the beginning of this chapter, a study was described comparing the hatch ratios of wood duck nesting boxes. Group I nesting boxes were well separated from each other and well hidden by available brush. There were a total of 489 eggs in group I boxes, of which a field count showed about 272 hatched. Group II nesting boxes were placed in highly visible locations and grouped closely together. There were a total of 821 eggs in group II boxes, of which a field count showed about 262 hatched. (a) Find a point estimate p̂1 for p1, the proportion of eggs that hatch in group I nest box placements. (Round your answer to four decimal places.) p̂1 = Find a 95% confidence interval for p1. (Round your answers to three decimal places.) lower limitupper limit (b) Find a point estimate p̂2 for p2, the proportion of eggs that hatch in group II nest box placements.
