let x be the sum of the 8 observations
then x/8 =40
x= 40×8=320
if 5 is added to each observation then the sum of observations will increase by(5×8) ie; the sum will be 320+40=360
then the new mean is 360/8=45
then x/8 =40
x= 40×8=320
if 5 is added to each observation then the sum of observations will increase by(5×8) ie; the sum will be 320+40=360
then the new mean is 360/8=45
