$\longrightarrow$ Here, no of observation are 9

Now,

$\begin{gathered}\implies \small \sf Average =\frac{23+33+33+27+25+68+27+44+72}{9}\\\end{gathered}$

$\begin{gathered}\\\implies \small \sf Average =\frac{56+60+93+71+72}{9}\\\end{gathered}$

$\begin{gathered}\\\implies \sf Average =\frac{116+164+72}{9}\\\end{gathered}$

$\begin{gathered}\\\implies \sf Average =\frac{352}{9}\\\end{gathered}$

$\begin{gathered}\\\implies \sf Average = 39.1 \\\end{gathered}$

$\longrightarrow$ The Average of given set of numbers is 39.1 .
