Question

The mean of 12 observations is 24 . If each observation is divided by 3,than find the new mean

Answer 1

The new mean is equal to 8.

• The mean of 12 observations is given as 24.
• Now each observation is divided by 3 and the new mean is calculated, for this we use the property of mean.
• The property states that if each observation in the data is divided by a constant k then the mean of the new data also gets divided by k.
• Therefore the new mean will be original mean divided by 3 that is 24/3 = 8.

Answer 2

Here is the ans

Step-by-step explanation:

sum of 12 observation/ 12=24

24 ×12 =28

288=sum of 12 observation

288*1/3////12=

=8
