JEE Main 2006 — Statistics Question with Solution
From: AIEEE 2006
Question
Suppose a population A has 100 observations 101, 102,........, 200, and another
population B has 100 observations 151, 152,......., 250. If VA and VB represent the
variances of the two populations, respectively, then is

Correct answer
A1
Step-by-step explanation
Series A = 101, 102 ............ 200
Series B = 151, 152 ............ 250
Here series B can be obtained if we change the origin of A by 50 units.
And we know the variance does not change by changing the origin.
So,
Series B = 151, 152 ............ 250
Here series B can be obtained if we change the origin of A by 50 units.
And we know the variance does not change by changing the origin.
So,
