Question :-

What is the mean of 34, 54, 67, 56, 11, 56, 78 ?

Concept Implemented :-

$\bigstar\;  \bf{Mean = \dfrac{\textbf{Sum of observations}}{\textbf{Number of observations}}}$

Solution :-

$\bigstar\;  \bf{Mean = \dfrac{\textbf{Sum of observations}}{\textbf{Number of observations}}}$

$\sf{\implies Mean = \dfrac{34  +54+67+56+11+56+78}{7}}$
