a random sample of 10 subjects have weight with a standard deviation of 13.1392 kg.what is the variance of their weight ​

Respuesta :

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
