Question

Given the population of numbers 3,6,8,9 and 4. Suppose samples of size 3 are drawn from this population.

Construct the sampling distribution of sample means.

Answer 1

$\mu (3,6,8)=5.67$

$\mu(3,6,9)=6$

$\mu(3,6,4)=4.3$

$\mu(3,8,9)=6.67$

$\mu(3,8,4)=5$

$\mu(3,9,4)=5.3$

$\mu(6,8,9)=7.7$

$\mu(6,8,4)=6$

$\mu(6,9,4)=6.3$

$\mu(8,9,4)=7$
