Answer 1

Answer:

$\huge{\underline{\underline{Given→}}}$

$\rm\green{Observations=17,15,18,15,10}$

$\rm\green{No.of\:observations=5}$

$\huge{\underline{\underline{To\:Find→}}}$

$\rm\purple{Mean\:of\:the\:given\:data}$

$\huge{\underline{\underline{Answer→}}}$

${\boxed{\red{\dashrightarrow}{\rm{\red{Mean=\dfrac{\rm{\small{Sum\:of\:all\:observations}}}{\rm{\small{No.of\:observations}}}}}}}}$

$\rm\blue{→\bar{x}=\dfrac{17+15+18+15+10}{5}}$

$\rm\blue{→\bar{x}=\dfrac{75}{5}}$

$\rm\blue{→\bar{x}=\dfrac{\red{\cancel{\blue{75}}}}{\red{\cancel{\blue{5}}}}}$

$\rm\blue{→\bar{x}=15}$

${\boxed{\boxed{\rm{\pink{→\bar{x}=15✔}}}}}$

☞ Hence the mean of the given data is 15 which is the required answer.
