I believe this is how you solve it
The option D is the correct option.
According to the statement
we have to define the sample variance in the words.
So,
The sample variance is the sum of the squared deviations from the mean divided by the number of measurements minus one.
and in the case of the population variance it becomes
The population variance is the average of the squared distances of the measurements on all units in the population from the mean.
This is the method by which we define the sample variance and population variance.
So, The option D is the correct option.

X + 12 = n
N is 5 more than twelve so add 5 to 12 and you get 17.
Put the second equation so it's in y= form, it should be the same :)
3(x-8)=12
I got this equation since there are three of the "x-8" sections that add up to the twelve length bar above
