Question

if the mean of 16 numbers is 8. Now, 2is added to every number, what will be the new mean?​

Answer 1

Answer:

There are 16 numbers, and their mean is 8.

Let their sum be S. So mean = S/16 =8.

If two is added to each number , the sum increases by 16 x 2 = 32.

To find the mean we divide by 16, so mean = (S+32)/16 =8+2 =10

Hence the new mean is 10

Answer 2

Answer:

10

Step-by-step explanation:

The mean of 16 numbers = 8

if 2 is added to every number , the mean value is also added by 2

so, 8+2=10
