Answer:
Option B.
Step-by-step explanation:
Given information:
Σ(x − M) = 44
where, M is mean.
Sample size = 12
The computational formula for sample variance is
[tex]s^2=\dfrac{\sum (x-M)^2}{N-1}[/tex]
where, M is sample mean and N is sample size.
Substitute Σ(x − M) = 44 and N=12 in the above formula.
[tex]s^2=\dfrac{44}{12-1}[/tex]
[tex]s^2=\dfrac{44}{11}[/tex]
[tex]s^2=4.0[/tex]
The sample variance is 4.0.
Therefore, the correct option is B.
