Answer:
B. Yuri divided by n instead of n-1
Step-by-step explanation:
It was stated in the question that the dataset was sample dataset. For a sample dataset, the standard deviation is given by the formula,
σ = √ Σ (Xi - mean)²/(n - 1) where i = 1,2,3.....n
Since this is just a sample dataset and not the whole population, Yuri should have divided by n-1 instead of n.
176 divided by 8 = 22
So 176 can be evenly divided by 8
Yes it is linear since it's in the standard form Ax+By = C
A = 2
B = -8
C = 16
