The logic followed here is: In all of the above number pairs, the second number is the square of the first number, except for one pair. 15 × 15 = 225
18 × 18 = 324
21 × 21 ≠ 420
12 × 12 = 144
17 × 17 = 289
The number pair (21 - 420) does not follow the pattern.
If the population kurtosis of the observations 16,12,6,2,4,10 is 1.7414, then population kurtosis of the 8,6,3,1,2,5 is
