Answer:

$\boxed{ \bold{ \huge{ \boxed{ \bold{ \sf{25.75}}}}}}$

Explanation:

Given data : 20 , 25 , 28 , 30

Σx ( sum of all the items ) = 20 + 25 + 28 + 30 = 103

N ( total number of items ) = 4

Finding the mean

To find mean of the given data , divide the sum of all the items by the number of items.

$\boxed{ \sf{mean = (sum \: of \: all \: the \: items)/(the \: number \: of \: items)}}$

$\longrightarrow{ \sf{ (103)/(4)}}$

$\longrightarrow{ \sf{25.75}}$
