Answer 1

$\huge \color{red}\overline \color{red} \underline {\color{yellow}{\fcolorbox{red}{cyan} {\tt{Answer}}}}$

$\sf \: Mean = \frac{sum \: of \: all \: observations}{total \: no. \: of \: observations}$

$\sf \: Mean = \frac{30 + 39 + 37.33 + 39 + 40 + 31 + 36 + 35 + 40}{9} = \frac{327.33}{9} = 36.36$

So mean of the given data is 36.37
