Answer:
Step-by-step explanation:
Given : A random sample of 10 subjects have weights with a standard deviation of 11.9407 kg
i.e. [tex]\sigma = 11.9407[/tex]
Since we know that the value of variance is the square of standard deviation.
i.e. [tex]\text{Variance}=\sigma^2[/tex]
Therefore, to find the value of variance, we need to find the square of the given standard deviation.
i.e. [tex]\text{Variance}=(11.9407)^2=142.58031649\approx142.58\text{squared kg}[/tex]
Thus, the variance of their weights =[tex]142.58\text{squared kg}[[/tex]
