The mean of 12 nu

Answer :

Given that, mean of 12 numbers = 48

Mean can be given by

Where, x = Sum of all observations

& n = Total number of observations

Here, Mean = 48 and n = 12.


x = 48 × 12

x = 576

We have sum of all observations = 576

If 4 is multiplied by each of the 12 numbers, then the new sum of all observations = 576 × 4

New sum of all observations = 2304

Now, we have fresh data: x’ = 2304, n = 12

New mean = 192

Thus, new mean of the observation is 192.
