Answer 2

Given:

If the number 66 replaced 30 in 93 , 50, 78, 46, 63, 30, 91 , then the range w

Solution:

Know that,

$\[{\rm{Range}} = \,{\rm{Max}}\,{\rm{value}}\, - \,{\rm{Min}}\,{\rm{value}}\]$

Find the range of 93 , 50, 78, 46, 63, 30, 91

$\[\begin{array}{l} = 93 - 30\\ = 63\end{array}\]$

Find the range after replacing 30 by 66 i.e. 93 , 50, 78, 46, 63, 66, 91

$\[\begin{array}{l} = 93 - 46\\ = 47\end{array}\]$

Hence the range of the data will decrease after replacing 30 by 66.
