The variance of the first 50 even natural numbers is

Answer 1

Hi dear ...
Here is U Answer......could u plsss mark it as brainlist answer plsss ...plsss...



Variance =∑xi2N−(x¯¯¯)2∑xi2N−(x¯)2

σ2=22+42....100250σ2=22+42....100250

=(2+4+....100)250=(2+4+....100)250

=4(12+22+32....+1002)50−(512)=4(12+22+32....+1002)50−(512)

=4(50×51×10150×6)−(51)2=4(50×51×10150×6)−(51)2

=3434−2601=3434−2601

σ2=833

Hope this answer helpful for u
