Answer:
The variance of their weight σ² = 172.63kg
Step-by-step explanation:
Explanation:-
Given sample size 'n' = 10
Given weight of the standard deviation (σ) =13.1392
we know that standard deviation (σ)=√ variance
The variance of their weight σ² =(13.1392)²
σ² = 172.63
The variance of their weight σ² = 172.63kg
