Answer:
49.4
Step-by-step explanation:
Mean = sum of observation ÷ total no ob observation
Given
Mean of 5 observation =45.5
Let the sum of 5 observation =x
45.5 = x/ 5
x =45.5×5=226.5
x=226.5
As total was short by 20.5
So we add 20.5 in x
Correct sum of observation =x+20.5=247.0
NEW Mean =247÷5=49.4
