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 =
