Question

find the mean if the observation 12,17,3,14,5,8,7,5​

Answer 1

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{ \boxed{\boxed { \huge \mathcal\red{ solution}}}}$

we know that

$we \: know \: that \: mean \: of \: an \: observation \\ \implies \boxed{ \frac{sum \: of \: observation}{number \: of \: trials} }$

given data are 12,17,3,14,5,8,7,5

so the mean is

$\implies \frac{12 + 17 + 3 + 14 +5 + 8 + 7 + 5 }{8} \\ \implies \frac{71}{8} \\ \implies8.875$

Hope this helps you....
