Answer 2

Step-by-step explanation:

Consider a data of three terms.

Let the three terms be a,b and c.

Hence, the mean is p=(a+b+c)/3. -----(1)

Let us add 5 to each term.

The terms become a+5,b+5 and c+5.

The new mean is (a+5+b+5+c+5)/3=(a+b+c+15)/3

=(a+b+c/3)+(15/3)=p+5.

Hence, if 5 is added to each observation of a set, the mean becomes mean+5.
