Question

 A population consists of six scores: 11, 13, 15, 16, 17, and 19. If

a sampling distribution of size 3 is drawn from the population, what is the standard

error of the mean of the sampling distribution? complete solution

Answer 1

Population consists of the numbers 11, 13, 15, 16, 17, and 19

Sampling distribution of size 3 can be given as

Mean of sampling distribution is $= \dfrac{303.27}{20} = 15.16$

Then, Standard Error can be calculated using the formula,

$SE = \dfrac{s}{\sqrt{n}}$

s = standard deviation of sample mean.

n = 20.
