20 (20 1) (The business scenario for thes question is exactly the same as in the preceding problem.) There are four restaurants, identified as W. X, Y and Z to which we want to apply a hierarchical clustering model. The two input vanables used for clustering are total cost of leasing the premises in 2023 and total cost of salaries in 7023 The cost of lease and cost of salaries are on the same scale and have similar range for all four restaurants. The table flows resulting Euclidean distance values, measured in dollars, between all pairs of restaurants For example, the Euclidean distance between Restaurant X and Restaurant Z is $12,000 zen want W Restaurant X Restarsrent Y testaurant X 2.600 krstaurant Y 2 500 12,000 18.000 Suppose the analyst arberandy forms two clusters one cluster is the pair (X, Y) and the second cluster is the pair (W, Z). If the single linkage the distance between these two clusters? O A 7 500 O B. 9:000 C 9400 O D. 9,890 O E 12000
