Centroid interpretations. The n-vectors x 1 ,...,x N contain n attributes of N patients

admitted to a hospital. The first component, (x i ) 1 , is the age of patient i. The second component,

(x i ) 2 , is 1 if the patient is having trouble breathing, and 0 if not. The third component,(x i ) 3 , is

the body mass index of the patient. (The other components give other attributes.) A QBUS1040

graduate carries out k-means on this data set, with k = 25. She finds the 18th centroid or group

representative is z 18 = (41.7,0.36,19.8,...,29.6). Give a simple short interpretation in English of the first three components.
