Answer 2

            $\rule{50}{1}\large\textsf{\textbf{\underline{Question:-}}}\rule{50}{1}$

         What is the mean of the following data values? 23, 79, 81, 10, 62

            $\rule{50}{1}\large\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}$

       First, we add all the data values:-

$\Large\text{23, 79, 81, 10, 62}$

$\bigstar$ On simplification,

$\large\textit{255}$

$\dagger$ Now, divide by the number of data values (5):-

$\large\text{255:5}$

$\triangle$ Which results in:-

$\Large\textit{Mean=51 (Option D)}$

Good luck with your studies.
