Answer 1

$Ages \: \: in \: \: Ascending \: Order \: \: : \\ 26, \: 28, \: 29, \: 31, \: 33, \: 33, \: 34, \: 37, \\ 41, \: 42, \: 44, \: 45, \: 47, \: 51, \: 56 \\ \\ Mean = \frac{Sum}{No \: \: of \: \: Terms} \\ = \frac{577}{15} \\ = \boxed {\underline{ \underline{38.46 \: \: that \: \: is \: \: 39}}} \\ \\ Median = Middle \: \: Number \\ = \boxed {\underline{ \underline{37}}} \\ \\ Mode = Number \: \: which \: \: is \: \: repeated \\ more \: \:times \: \: than \: \: other \: \: numbers \\ = \boxed {\underline{ \underline{33}}}$
