Question

Find the sample mean x for each possible sample of size n = 2. Sample 4, 6 4, 8 4, 10 SampleX 6, 8 6, 10 8, 10 T. (Type integers or decimals rounded to two decimal places as needed.) 2

Answer 1

$\dpi{100} \fn_cm \mathbf{Solution}$

$\dpi{100} \fn_cm \mathbf{Mean\;(\bar x)}=\frac{\sum x}{n}$

$\dpi{100} \fn_cm \mathbf{Sample }$	$\dpi{100} \fn_cm \mathbf{\bar x}$	$\dpi{100} \fn_cm \mathbf{Sample }$	$\dpi{100} \fn_cm \mathbf{\bar x}$
4,6	$\dpi{100} \fn_cm \frac{4+6}{2}={\color{Red} 5}$	6,8	$\dpi{100} \fn_cm \frac{6+8}{2}={\color{Red} 7}$
4,8	$\dpi{100} \fn_cm \frac{4+8}{2}={\color{Red} 6}$	6,10	$\dpi{100} \fn_cm \frac{6+10}{2}={\color{Red} 8}$
4,10	$\dpi{100} \fn_cm \frac{4+10}{2}={\color{Red} 7}$	8,10	$\dpi{100} \fn_cm \frac{8+10}{2}={\color{Red} 9}$
