Answer 1

Answer:

here n=10

table for rank correlation

ranks in A : 1 6 5 10 3 2 4 9 7 8

ranks in B 3 5 8 4 7 10 2 1 6 9

ranks in C: 6 4 9 8 1 2 3 10 5 7

x= (A-B) ² : 4 1 9 36 16 64 4 64 1 1 = 200

Y=(X-y) ²: 25 4 16 4 4 0 1 1 4 1 = 60

z= (Y-z)² : 9 1 1 16 36 64 1 81 1 4 = 214

from the Calculation we can see that A and c has common liking in music
