Answer:
Step-by-step explanation:
Sample variance when large number of samples are drawn we have tend to become a normal distribution.
Variance of the sample is different since variance
Var(x) = E(x^2)-{E(x)}^2
is the formula used for finding the variance of any sample.
But sampling distribution of variance requires repeating this process with the different samples several times.
So option A is not right
B is also not correct, C is wrong
D.The sampling distribution of the mean requires multiple samples to be compared. However, in this situation you are looking for the variance, so finding the sample variance is the same as investigating the sampling distribution of the variance.
is correct
Answer:
{2,3,4,5}
Step-by-step explanation:
Domain is the set of x-values for which the function is defined.
Range is the set of y-values for which the function is defined (set of values corresponding to the set of x-values).
The function is given as 
The domain is (-2,0,2,4)
That means, we need to plug-in the 4 numbers given into x of the function and find the 4 corresponding y values (the range).
So, lets do this:
putting x = -2,

putting x = 0
y = 3
putting x = 2

putting x= 4

Thus, the range is {2,3,4,5}
You can multiply 16 times what equls 88 and then divide by 4 much more simple than it sounds and also your in high school and u cant solve this problem
