Question
If 5 is added to each and every item of a data, then the A.M is
- 5 times to the first A.M.
- increased by 5 to the first A.M.
- equal to the first A.M.
- decreased by 5 to the first A.M.
The correct answer is: increased by 5 to the first A.M.
Let 
be the original observations of the data.
Let there are total n number of observations in the data.
Sum of original observation = n X original mean
, where 
is original mean of data.
Since 5 is added to each and every item of the data
Each observations of new data is of type 
.
Sum of new observations =
