Answer 2

Question :-

To find range and mean.

Solution :-

$⇝\bold{range \: = L - S}$

highest one - smallest .

$\bf⇝ mean = \frac{total \: observations }{no. \: of \: observations }$

$\sf \:in \: ascending \: order: - \\ \sf12,13,13,14,15,16,17,18,18,21$

$\sf \bullet \: \: l \: = 21 \\ \sf \bullet \: \: s = 12 \\ ⇝\sf \: range = 21 - 12 = 7$

$\sf \: mean = \frac{12 + 13 + 13 + 14 + 15 + 16 + 17 + 18 + 18 + 21}{10} = \frac{157}{10}$

$⇝\sf \: mean = 15.7$

$\bf\red{ range = 7}$

$\bf\blue{mean = 15.7}$
