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

where, M is sample mean and N is sample size.
Substitute Σ(x − M) = 44 and N=12 in the above formula.



The sample variance is 4.0.
Therefore, the correct option is B.
Answer:
Just take the two zeros to 100
Step-by-step explanation:
What how is this a problem and how are you in middle school
45 times the numerator plus the denominator is most likely going to equal the same amount as if it were doubled.
